Verify a Number, Trace a PIN Code, or Confirm a Bank Branch, All From One API
Roundpay brings together three genuinely useful lookup tools under one roof: HLR Lookup for telecom data, a Pincode Finder for India's postal system, and an IFSC Code Finder for banking transfers. Each one solves a different everyday problem for developers and businesses.
Whether you're integrating into a web form, mobile app, third-party service, or desktop program, you can get HLR Lookup Integration running in your service in under 3 minutes. This makes it one of the more practical ways to integrate the HLR lookup API into software you're already building, without a lengthy setup process.
HLR stands for Home Location Register (HLR), the core database telecom networks use to store subscriber information. Our HLR Lookup API taps directly into this signaling network lookup to tell you which network a number belongs to, in real time.
Our platform also supports a free mobile number tracing tool. You can use this for tracing or looking up any Indian mobile number in a standard 10-digit format, and the tool shows you the general location of the mobile phone on a map.
Results also show the Telecom Operator and the signaling network used by that mobile phone. We maintain a complete database covering every Indian telecom operator, so nearly any Indian mobile number can be traced through this system. It's genuinely useful as a Mobile Number Operator Finder for call centers, KYC checks, and fraud prevention teams alike.
For developers building this into their own stack, our HLR Lookup API for developers, also usable as a standalone Telecom Operator Detection API, comes with clear documentation, so a Real-time mobile number operator check API call returns exactly what you need: operator name, circle, and Telecom circle/state detection, without extra parsing on your end. It's the most direct way to find mobile operator by number India-wide, whether you're checking one number or running it across a large dataset.
We also help detect Mobile number portability (MNP) cases, so if a number has switched operators while keeping the same number, your system reflects the current operator rather than the original one. Alongside operator data, results also include Mobile Network Code (MNC) and Mobile Country Code (MCC) values, useful for systems that need standardized telecom identifiers rather than just an operator name.
Postal Index Number, or PIN, or Pincode, is the numbering system used by India Post as part of its postal framework. The PIN code is 6 digits long. The first digit reflects the region, the second the sub-region, the third the sorting district, and the last three represent the specific post office code. India has nine PIN zones in total.
India is a large country, and it's close to impossible to remember the PIN code for a specific area in every city, town, or village, or to locate a place using only its PIN code. That's exactly the gap our Pincode Finder India tool fills.
When sending a letter or a package through the Indian postal system or by courier, the chances of it safely reaching its destination go up significantly whenever you remember to include the correct PIN code for the destination.
India is such a vast country, with so many cities, towns, and villages, that finding the right place or person can be a genuine challenge, both for India Post and for courier services. To make the process of delivering letters and packages more efficient, the Indian postal service introduced the 6-digit Postal Index Number on 15 August 1972, as part of the broader India Post PIN code system still in use today.
If you need to search PIN code by area/city India-wide, our PIN Code Search Tool works both ways: look up a PIN code by area name, or look up the area details for a given PIN code, through the same Postal Code Lookup India interface.
IFSC is short for Indian Financial System Code, an 11-character code you'll typically find printed on your bank's cheque leaves or other bank-issued documents. This 11-character code identifies the specific bank branch participating in various online fund transfer options like NEFT and RTGS.
The IFSC Code of the destination branch on the payee's account is required to complete most online transfers. When it comes to finding an IFSC Code, you simply use our IFSC Code Finder online, available directly through Roundpay. This smart, easy-to-use IFSC Code Search Online tool helps with the IFSC lookup for various banks. Its best feature is that, alongside a standard IFSC search, it also shows you the bank name by IFSC code, branch name by IFSC code, and branch address by IFSC code, giving you a real Bank Branch Finder by IFSC in one lookup.
IFSC Code: Key Features
IFSC, short for Indian Financial System Code, is a unique 11-digit alphanumeric code used for online fund transfer transactions carried out via NEFT, RTGS, and IMPS, each one an NEFT/RTGS/IMPS transaction code type that depends on a valid IFSC to process. A bank's IFSC code can usually be found on the cheque leaf issued by the bank. Every one of these codes is assigned to banks by the Reserve Bank of India (RBI), and anyone can look up IFSC codes for banks and branches directly through the Reserve Bank of India (RBI) IFSC directory. Net banking transactions for fund transfers, using any wire transfer mode, can't be initiated without a valid IFSC.
If you're specifically looking for an IFSC code finder for NEFT, RTGS, or IMPS transactions, or want a free IFSC code finder online tool without any signup required, this same lookup covers both needs. Beyond just the code, our Bank branch address lookup also returns the full branch address by IFSC code, useful for anyone doing bank name and branch by IFSC code verification before initiating a transfer.

HLR lookup is a way to query the Home Location Register (HLR), a telecom database, to find out details about a mobile number, including which network it currently belongs to and whether it's active.
You can run the number through an HLR Lookup API, which checks it against the signaling network and returns the current Telecom Operator, along with details like MNC, MCC, and circle information.
A PIN code, or Postal Index Number, is a 6-digit code used by India Post to identify a specific post office and sorting area, part of the broader India Post PIN code system introduced in 1972.
An IFSC code is an 11-character alphanumeric code used to identify a specific bank branch during electronic fund transfers like NEFT, RTGS, and IMPS, ensuring the money reaches the correct branch without error.
You can find it printed on a cheque leaf issued by that bank branch, or by searching through our IFSC Code Finder using the bank name and branch, which also returns the branch address.
