Update Mobile & Alternate Numbers

Overview

The PT Update Number & Alternate Number feature enables secure management of mobile contact details associated with a property in the DIGIT Property Tax system. It allows both citizens and ULB employees to correct or enhance owner contact information to ensure reliable communication, authentication, and service delivery.

Key Functionalities

The functionality supports:

• Updating the primary mobile number when the existing number is invalid, outdated, or inaccessible.
• Adding an alternate mobile number as a secondary contact for notifications and login-related use cases.

The feature is tightly integrated with MDMS-based validation rules, OTP-based verification, and role-based access controls to maintain data integrity and security. Employee-driven updates can be supported with document uploads, while citizen-driven updates rely on OTP verification through the user service.

Overall, this capability improves data accuracy, reduces service disruption due to incorrect contact details, and enhances the usability of the Property Tax system for both citizens and administrators.

Configuration Steps

1

Configure MDMS

The MDMS drives validation rules and mobile number behaviour.

Configure an UpdateNumber section in MDMS

In your MDMS config for the PropertyTax module, include an UpdateNumber entry:

"MdmsCriteria": {
  "tenantId": "pb",
  "moduleDetails": [
    {
      "moduleName": "PropertyTax",
      "masterDetails": [
        {
          "name": "UpdateNumber"
        }
      ]
    }
  ]
}

Sample MDMS Response values:

• invalidNumber: e.g., "9999999999"
• invalidPattern: Regex like "^[6789][0-9]{9}$"
• skipEnabled, warningEnabled flags
• documents: list of documents required (can be empty)

This config tells the UI which numbers are invalid and how to validate new numbers.

API Endpoints

Use these Property Tax APIs for updating numbers:

Purpose	API Endpoint
Update main mobile number	property-services/property/_update
Add alternate mobile number	property-services/property/_addAlternateNumber

Steps to Update Primary Mobile Number

• User clicks Edit next to the existing owner's mobile number (in UI).
• A pop-up appears asking for the new mobile number.
• Click Send OTP → API sends OTP via user-otp/v1/_send for login.
• If the OTP send fails because the number isn’t registered, try with type=register to create the user.
• Enter the OTP — it verifies and validates the user.
• On success, the system triggers the property update call to persist the new number.

  • The API updates owner.mobileNumber.

Notes:

• Employee roles must upload supporting documents in the pop-up before proceeding.
• Employee updates skip the OTP send/verify steps because ownership validation is assumed.

Add or Update Alternate Mobile Number

1. Click Add Alternate Number in the property UI.
2. A pop-up opens to enter the new number.
3. The system sends OTP to the registered primary number via user-otp/v1/_send.
4. Upon OTP validation, the system triggers:

   • property-services/property/_addAlternateNumber, and
   • Sets owner.alternateMobileNumber

This allows an additional contact, useful for notifications or multi-contact alerts.

5

Configure Roles & Action Mapping

Ensure roles have permissions mapped to these API operations:

API	Action ID	Roles
property-services/property/_addAlternateNumber	870	CITIZEN, PT_CEMP
property-services/property/_update	954	CITIZEN, PT_CEMP
user-otp/v1/_send	1531	CITIZEN
property-services/property/_search	1897	CITIZEN, PT_CEMP

Configure these in your role-action management so that both citizens and employees can perform these updates securely.
