You might be surprised, but the default limit in Zoho FSM is 15 (sic!)
Addresses per record. It’s an odd restriction, but it can be raised for a particular Zoho FSM instance. We encountered this limit ourselves while working on a Zoho FSM project for a roofing company. If you want to increase the number of Service Addresses per record in your Zoho FSM,
let us know; we know the ways.
