Found dog adoption

I found a dog walking around my neighborhood a couple weeks ago. I gave her water and fed her and she did not want to leave after that. I’ve been walking her through every near by street to see if the owner comes forward, but had no luck. My wife walks her in the morning and I walk her in the evening every day. I took her to the vet to see if she was chipped. Turns out she is registered with akc. The owner has not come forward. I was asked if I can hold her for the 14 day period while they try to get her back home and I accepted. The 14 days passed and I did not receive a call back.

Am I able to adopt her? Would I be able to get the akc registration?
