If the service area business has no physical address on GMB, can they still rank, and will the product work for them?

How does Proximity Booster work with Service Area Businesses

As a Service Area Business (SAB) has no visible location, it is a little more effort to get them to rank. Firstly we need to still build proximity out from the initial location where the SAB was setup. Most often this is the suppressed address of the business owner, however in some cases it may be a different location all together. Once we understand the location where it was set up, we can work out from there, all other optimisation techniques are the same, it may just take longer to reach its full potential.
