So I've decided to purchase a house in the Canyon Creek subdivision (in between 15th St. and 29th St. on Mustang Rd.), and I was under the impression that the property was in OKC. However, the contract listed the zip code as 73099, which I know to be a Yukon zip.

I Googled the address, and everything lists the property as being a Yukon residence. I recall reading about Yukon annexing some land from OKC, but this seems to be a bit far south from what I remember. Could the zip be throwing off Google, or is this really Yukon?
