## What the Address Lookup by Mobile API does

Address Lookup by Mobile returns the addresses linked to a mobile number. For each one it gives the complete address, the address lines, city, state, pincode, the data sources it came from and the date it was last seen.

The last seen date shows which addresses are current, so you can check an address a customer has declared against the ones linked to their number, or find where to reach them.
