To check how many mobile numbers are registered under your NRIC in Singapore, use the official SIM Card Checker by the Infocomm Media Development Authority (IMDA). It securely lists all postpaid SIM cards registered to your ID across all local telecom providers. [1]
How to Check
  1. Visit the SIMCardHowMany Portal.
  2. Log in securely using your Singpass.
  3. Enter your email address and verify it with the 6-digit code sent to your inbox.
  4. You will receive an automated email from info@plumber.gov.sg containing the full list of postpaid mobile numbers registered under your NRIC. [1, 2, 3]
What to Do Next
If you spot unfamiliar phone numbers, contact your telecom provider immediately to verify or terminate the unauthorized lines to prevent your details from being misused. [1, 2]
Note: As of early 2026, the cross-telco limit allows each individual to register a maximum of 10 postpaid SIM cards. [1, 2]
