# 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
