You're probably better taking it to a vet to check for a chip. Might save you some time if all of its shots are registered, plus you will know if there is a family somewhere tripping. I am not certain, but if you take him/her to the shelter they might could check for a chip, but you also may be looking at surrendering for a mandated period of time and paying to walk away the same you came in, but I may be wrong.
I'm not sure but call them and ask them.
