Does Verified Campaigns allow the sharing of Phone Number field in SHA 256 Hashed format?

Yes, Truecaller supports the use of SHA-256 hashed values for PII fields such as phone numbers. This allows businesses to maintain data privacy and security while still leveraging Truecaller’s Verified Campaigns capabilities

When using hashed inputs:

  • The phone number must be in 12-digit format (e.g., 91XXXXXXXXXX), without the plus sign.

  • Apply SHA-256 hashing to the 12-digit number.

  • Send the lowercase hexadecimal string in the payload.

Example:

  • Raw phone number: 911234567891

  • SHA-256 Hash: efc187bdaca8e73ddffb1b4615e9652bb775721335bc97f47888dfebd9058444
