wiring funds to Oxxo or Coppel

Sorry to revisit an old topic but I ran into a snafu trying to wire funds to my cuidador in zihua and want to use Western Union for maybe 3 times during this low season.

I know that the recipient must have a valid Mexican ID to pick up funds in addition to a tracking number, are their any other requirements a recipient to obtain the funds?

If the funds are sent by Western union to say Oxxo or Coppel, do I, as the sender need to identify the specific street address or store number of the Oxxo or Coppel location?

Gracias
