Address related fields in GST

Effective July 4th, 2024, the government has introduced several enhancements to address-related fields in GST registration functionalities, including New Registration, Amendment Application (Core & Non-Core), and Geocoding Business Addresses. These changes are based on user feedback and analysis of reported issues.

In this blog, we will cover the updates, as well as the benefits and challenges for users.

Key Updates:

  1. Validation Updates for Address Fields
    For Indian Addresses:
    - PIN Code, State, District, and City/Town/Village: Must be selected from autosuggestions.
    - Other Fields: Alphanumeric values and limited special characters are allowed (e.g., -, /, &, ,, ', #, ., (), "", :, ;, _, and space). Special characters cannot start the entry.
    - Example: "123 Main St. #4, Apt (5A)" is valid, but "#123 Main St." is not.
    For Addresses Outside India:
    - Zip Code, State, District: All values except `{}` are allowed.
    - Other Fields: Similar rules as for Indian addresses apply. Special characters cannot start the entry.
  2. Input Instructions
    - Detailed instructions for allowable input values are available when hovering over the relevant icon in the address fields.
  3. Data Integrity
    - Existing data in the system remains unchanged, even if it includes now-disallowed special characters. However, editing address details in an amendment application will trigger validation based on the new rules.
  4. User Feedback Implementation
    - These changes address common issues where users were unaware of the allowed characters or editable fields. For instance, users often inserted a hash (#) at the beginning of the Building Number field, which is no longer permitted.
  5. Applicability
    - These updates apply to Normal Taxpayers – Regular, SEZ Unit, SEZ Developer, Composition, Input Service Distributor, and Casual Taxpayers.
  6. Locality/Sub-locality Field
    - The Locality/Sub-locality field is no longer mandatory.
    - If left blank or mapped incorrectly, the system will display a warning: "Locality/Sub-locality does not match the Pin Code. Do you want to save the details?" or "You have not filled in Locality/Sub-locality. Do you want to save the details and proceed further?"
    Example: If you enter Pin Code 123456 but leave the Locality/Sub-locality field blank, you will see the message: "You have not filled in Locality/Sub-locality. Do you want to save the details and proceed further?" Click "YES" to proceed.

Impact on Work


  1. Increased Accuracy:
    - The interlinked fields and autosuggestions ensure that the entered address details are consistent and accurate, reducing errors during registration and amendments.
  2. Improved User Experience:
    - Clear input instructions and helpful warnings streamline the registration process, making it easier to fill out forms correctly the first time.
  3. Compliance:
    - Ensuring addresses are entered correctly helps maintain compliance with GST regulations, avoiding potential issues with incorrect or incomplete addresses.


  1. Learning Curve:
    - Users may need time to adapt to the new validation rules and input instructions, especially if they were previously unaware of the allowed characters and formats.
  2. Data Correction:
    - Although existing data remains unchanged, any amendments requiring address updates will need to adhere to the new rules, potentially necessitating corrections to previously acceptable entries.
  3. System Warnings:

    - Users might find the new warning messages for Locality/Sub-locality fields initially confusing or disruptive, requiring a period of adjustment.

    These enhancements aim to streamline the GST registration process, improve data accuracy, and enhance the overall user experience, ultimately leading to more efficient and compliant address management.
