Each jail or prison system has their own rules about what can be sent in for prisoners, if anything, so you will need to find out from him, or from the jail. The same is true for inmate locator web pages, they are specific to the jail/prison where he is housed, and there can be a delay for new prisoners.
If he is in Oklahoma County, here's their web page.

If he is in a different County jail, do a google search to find that information.
