You can use Pos Indonesia address validation to cross-check whether your customers’ delivery addresses are accurate, complete, and deliverable.

This blog discusses everything about Pos Indonesia address validation and how it works. It will help you determine whether this tool is correct for your business, who can use it, and its limitations.

Key Takeaways

  • Pos Indonesia address validation helps businesses know whether their customers’ mailing addresses are correct and deliverable. They can make changes to the delivery data according to the results. 
  • Pos Indonesia offers a postcode finder to let you find and add correct postcodes to your delivery addresses. You can also locate the nearest post office using the postal website to avail yourself of its services. 
  • Businesses must consider an alternative if they require geocoding, address autocomplete, standardization, secondary address units, and other features that Pos Indonesia doesn’t provide. 
  • PostGrid’s Address Verification API helps you autocomplete, standardize, geocode, and validate your customers’ mailing addresses at reasonable costs.

What is Pos Indonesia Address Validation?

It is a solution businesses use to ensure they send mailpieces to the correct recipients. Though many companies still rely on users’ manual inputs, verifying their mailing details is recommended to prevent delivery failures. Also, checking the accuracy of hundreds and thousands of addresses can be challenging and lead to several mistakes. 

Pos Indonesia address validation allows businesses to ensure customer satisfaction by promptly fulfilling their orders. Imagine some people shopping for high-end products on your website and completing payment. Your website shows them an estimated arrival time of three business days. Typically, your business packs and sends the orders after one business day; the shipment takes another two days to arrive. However, what happens when you post the item for shipping but Pos Indonesia delays it by another five to six days?

Yes. It hampers your brand reputation and might lead to customer dissatisfaction. They might switch to a competitor and also spread negative publicity. However, Pos Indonesia is not at fault because you didn’t verify the mailing address. Pos Indonesia address validation helps determine whether the address is valid and serviceable. Otherwise, you can use another courier service to complete fulfillment. Other benefits of using Pos Indonesia address validation are:

  1. Cutting reshipping expenses: Businesses can avoid getting mail returns and reshipping the items if they send the mailers to the correct addresses. They can prevent spending a fortune on postage expenses by ensuring the correct recipients get the items. 
  2. Saving time and labor: You can save your employees’ time and manual effort by incorporating an online address verification tool instead of asking them to check all addresses manually. They might have to call every customer to confirm their addresses, which is impossible if the number of customers is vast. 
  3. Expanding your coverage: Pos Indonesia address validation allows you to grow your business beyond local and regional locations. You can serve a broader audience by cross-checking their delivery addresses and sending buyer communications without hassle.

How Does Pos Indonesia Address Validation Work?

Unlike USPS, Pos Indonesia doesn’t have a dedicated tool to help you verify customers’ mailing addresses. Hence, you cannot enter an address into a field and get the results instantly. However, you can use their postal website for other ways to facilitate the use of post office services for your business:

Find Post Offices

You can visit Pos Indonesia’s website to locate post offices in your locality, neighborhood, or city. It shows you a map of different places, which you can navigate to find your preferred location. You can get the details of the post offices in that area, helping you avoid traveling long distances to ship your letters and parcels. 

Find Postcodes

This Pos Indonesia address validation tool allows you to find the correct postcodes corresponding to your mailing addresses. It is crucial to mention the postcode at the end of Indonesian addresses to ensure the post office can route your shipments properly and ensure fast deliveries. Otherwise, your mail might end up in entirely different cities and provinces than what you mentioned in them. 

You can enter the location and postcode with the province to get the results. If unsure, add the city name in any field and click “Search.”

However, these results aren’t refined, leaving 14 pages to filter your desired postcode. Hence, you must always get as much information as possible to use this tool correctly and not have hundreds of results to sort.

Track Packages

You cannot use Pos Indonesia address validation to learn whether your address is accurate and valid. However, you can track your mail to see if they are headed to the correct destinations. If not, you can take preventive measures like informing the post office and requesting a route change. Also, you can update your customers about potential delays. 

The tracking tool is simple and quick. You can enter your entire tracking number and the security code (that acts like a CAPTCHA) to get the delivery status. 

Who Uses Pos Indonesia Address Validation?

Healthcare Organizations

They use Pos Indonesia Address Validation to ensure that client addresses are correct and complete. It is also crucial to send medical bills, test results, and medicine to accurate patient addresses. Hospitals, clinics, and pharmacies need deliverable addresses to avoid delivery problems or delays. It also helps with patient records, ensuring every person’s contact details are current. 

Healthcare teams can send crucial health reminders or follow-up messages with the correct addresses. It helps improve patient care and facilitates communication between healthcare providers and patients. Address validation helps healthcare companies run better and avoid costly mistakes.

Insurance Companies 

These businesses use Pos Indonesia address validation to ship correspondence letters, policy documents, and claim updates to the right place. Customers might not get their documents on time if the address is wrong. Correct addresses also help insurance agents contact customers easily for renewals or updates. It also reduces the risk of fraud because the company knows where the customer lives. With accurate addresses, insurance companies can work faster, avoid delivery problems, and keep better records. This helps them give better service to their customers.

Financial Services

Banks, credit companies, and lenders need accurate addresses to send account statements, loan documents, and payment reminders to the correct place. Valid addresses also help when verifying customer identities to prevent fraud. If addresses are incorrect, significant documents with sensitive details might get lost or delayed, causing problems for the company and the customer. Pos Indonesia address validation helps financial companies maintain proper records, follow government rules, and improve customer service by ensuring all communication reaches the right person at the right time.

Logistics Firms

Pos Indonesia address validation helps delivery drivers find the correct mailing location faster and avoid delays. With correct addresses, packages reach customers on time without getting lost or returned. It also helps logistics companies save time and money by reducing mail returns. Accurate addresses improve tracking and ensure delivery updates go to the right customer. Whether they deliver small or large parcels, checking the address beforehand ensures everything runs smoothly. It also helps build trust with customers by providing reliable and fast deliveries.

Retail and Ecommerce

Checking address accuracy helps online stores deliver orders to the right place without delays or mistakes. With accurate addresses, packages do not get lost, returned, or sent to the wrong person. It also helps with faster shipping and better customer service. When addresses are correct; companies can update customers easily about their orders. It also saves money by reducing shipping errors and extra delivery costs. Also, address validation helps orders arrive safely and keeps customers happy for small online shops and big stores.

How to Write Addresses Correctly in Indonesia?

1. Write the Full Name of the Receiver

Start with the full name of the person, company, or office receiving the letter or package. Do not use short names or nicknames. Write the full name clearly so the courier knows precisely who the package is for.

Example:
Budi Santoso
Toko Jaya Abadi

2. Write the Street Name and Building or House Number

Write the street’s name first, followed by the house or building number. If the building has a special name, you can also mention that.

Example:
Jl. Merdeka No. 10
Jl. Raya Sudirman Blok A No. 15

3. Add RT and RW Numbers (If Needed)

You must write RT and RW numbers in many areas, especially residential neighborhoods. These neighborhood codes help the local post office or courier find the right area faster.

Example:
RT 03 / RW 05

4. Write the Village (Kelurahan) and Subdistrict (Kecamatan)

After the street and RT/RW, write the Kelurahan (village or urban area) and Kecamatan (subdistrict). These help narrow down the location further.

Example:
Kelurahan Sukamaju
Kecamatan Ciputat

5. Write the City or Regency

Next, write the city’s name (Kota) or regency (Kabupaten). Since many areas in Indonesia have similar street names, mentioning the city or regency helps avoid mistakes.

Example:
Kota Tangerang Selatan
Kabupaten Bogor

6. Include the Province

Always include the name of the province. Indonesia has many provinces, and writing the correct one helps the delivery process.

Example:
Banten
Jawa Barat

7. Write the Correct Postcode (Kode Pos)

Postcodes help sort letters and packages faster. Always check the correct postcode for the area and write it at the end of the address.

Example:
15419

Full Example Address

Budi Santoso
Jl. Merdeka No. 10
RT 02 / RW 03
Kelurahan Sukamaju, Kecamatan Ciputat
Kota Tangerang Selatan
Provinsi Banten
Kode Pos 15419

Tips for Writing Addresses Correctly in Indonesia

  1. Write Clearly: Always write the address clearly. Use easy-to-read writing if you are writing by hand. If you type the address, ensure the font is clear and big enough to read easily.
  2. Do Not Skip Any Parts: Write the address completely. Do not miss important details like street number, RT/RW, village, or postcode. Every part helps the delivery person find the correct place.
  3. Check Spelling Carefully: Always check the spelling of names, street names, and areas. Small mistakes in spelling can cause big delivery problems. Even one incorrect letter can cause your delivery to fail.
  4. Verify the Postcode: Postcodes are very important for sorting and delivery. Always check the correct postcode for the area before you write it. An invalid postcode can delay or send the package to an incorrect location.
  5. Use Standard Address Format: Follow the standard order: name, street, RT/RW, village, subdistrict, city, province, and postcode. This makes it easier for couriers and post office workers to understand the address quickly.

Pos Indonesia Address Validation Limitations.

Does Not Offer a Dedicated Address Verification Solution

Though Pos Indonesia provides many tools, like a package tracker and a postcode finder, it does not provide an address validation solution. Hence, you cannot enter an address and get verified results, making it an unreliable and incomplete method of checking delivery addresses before shipping. Instead, businesses must use an all-in-one address verification API, like PostGrid, to do the job.

Does Not Offer Geocoding

Pos Indonesia does not offer geocoding. Geocoding means turning an address into exact map coordinates, like latitude and longitude. With geocoding, businesses can see the location on a map, which helps with route planning, delivery tracking, or location-based services. Since Pos Indonesia address validation only checks if an address is serviceable, it does not provide this extra location data. Companies that need map coordinates for deliveries, site visits, or customer locations must use other mapping tools or geocoding services to get this information.

Cannot Verify Secondary Address Units

Secondary units include apartment numbers, office suites, or floor numbers in a building. It means the system might confirm the building address is correct, but it will not check if the apartment or office number exists or is right. It can cause delivery problems if the package only reaches the main building but not the correct unit inside. Businesses sending items to apartments, offices, or malls may need extra tools to check the main address and the exact unit number.

Does Not Provide Address Autocomplete

Autocomplete helps users by suggesting full addresses as they type, saving time and reducing typing mistakes. Without autocomplete, customers must type their full address manually, which increases the chance of errors like missing house numbers or wrong street names. Many modern address tools use autocomplete to make checkout or form-filling faster and easier, especially for online shopping or deliveries. However, Pos Indonesia does not provide this feature.

Cannot Check International Address Data

Pos Indonesia cannot check or confirm addresses in other countries. This is a limitation for businesses that must send packages, documents, or products to overseas customers. A company with international customers will need a different tool to check and validate those foreign addresses. This disadvantage can lead to delivery problems if the business does not address errors before shipping. Companies that work with global markets should combine Pos Indonesia address validation with other international verification tools to avoid these issues.

Can Only Help You Find Single Postcodes, Not Bulk

The tool does not support bulk postcode searches. Hence, if a business needs to check hundreds or thousands of addresses simultaneously, it cannot do it directly using Pos Indonesia’s service. Each address must be checked individually, which takes time and effort. For businesses with large customer lists, this is not practical. Companies needing bulk address or postcode validation must use other tools or software designed for handling large amounts of data simultaneously.

Better Alternative to Pos Indonesia Address Validation

Pos Indonesia doesn’t offer a concrete address validation tool. Instead, it helps individuals and businesses locate post offices to resolve queries, track packages, and verify postcode information. However, it isn’t enough to ensure accurate and timely deliveries. Your organization needs more than a post office tracker; it needs a solution to reformat addresses according to the postal guidelines and guarantee validity. 

Hence, always look for an address-checking tool to tell you whether your customers’ delivery addresses are correct. If not, it should suggest what modifications you must make to make them deliverable. Also, the solution must change the address format to suit the post office regulations of the destination country, irrespective of whether you send national or international mail. 

One such alternative is PostGrid’s Address Verification API. It allows you to enter an address in whichever form you have and get complete, updated, and verified results ready for mailing. You can also use this solution to improve your database quality and make informed marketing decisions based on customer location data!

PostGrid: Autocomplete, Standardize, and Verify Mailing Addresses

PostGrid’s Address Verification solution lets you get many advanced features in one tool. You can parse your addresses, which means breaking them down to identify different components, like the street name, city, province, and postcode. Also, you can reformat all delivery addresses to ensure these elements are correctly placed. 

As discussed above, you must follow the correct Pos Indonesia-prescribed address format when sending mailpieces. However, manually identifying and modifying every address’s layout can be challenging. Hence, PostGrid offers address standardization that works on reformatting your delivery addresses, be it one or a hundred thousand. 

Then, you can benefit from address verification, which involves finding a match for your address in the post office’s official database. PostGrid checks whether an address exists in Pos Indonesia’s records. If not, it marks the address as invalid. However, it is crucial to identify and correct the mistakes to locate a proper match. 

PostGrid also offers address autocomplete, helping users get adequate and correct address suggestions as they start typing their details in your address field. It cuts the keystrokes and saves their time, ensuring you can quickly and easily capture their accurate mailing data. 

The best part is that PostGrid provides these features together—at the same prices! Once you enter an address, it automatically parses, autocompletes, standardizes, and verifies it before showing you the results. The entire process takes a second or less. You can check up to a million delivery addresses in less than two hours!
