Fanocodi was a Roman place-name mentioned in the Ravenna Cosmography for a location close to the Solway Estuary; the name has been derived from Fanum Cocidii, or temple of Cocidius, and the place identified with Bewcastle.
The regiment was transferred from Dacia to Britain not later than 125, when it was stationed briefly at Fort Fanum Cocidi (Bewcastle, Cumbria) and appears to have participated in the excavation of the so-called Vallum, a huge ditch running along the near side of Hadrian's Wall (constructed 122-8).
