In GTA V, the company operates Mule fleet trucks. The Heists Update for Grand Theft Auto Online added the Boxville as another vehicle used by the company. The company has an office in Pillbox Hill, its own warehouse at the Terminal, a depository at Elysian Island and a depot on Paleto Boulevard in Paleto Bay.
The company appears as one of the main postal services in the HD Universe, alongside GoPostal, Liberty State Delivery and Alpha Mail. Mailmen for the company can be seen in GTA IV, but they are rare to find. They are, however, more common in GTA V.

- Its name is a reference to a male-to-female gender reassignment operation, "post op" being short for "post operation". The company's slogans, "No longer just mail" and "Your package is safe in our hands", also reference this.
- The company's logo is also a play on the phrase "axe wound", a euphemism for female genitalia. The postal box flag appears like an axe above a gash (another euphemism..), hence the "axe wound" and the "gash" - appropriate terms for the reassigned genitalia.
- In the game files of GTA V, the Post OP worker character models are named "Ups 1" and "Ups 2", a clear reference to United Parcel Service.
