Caller ID Name generally uses a lookup table provided by your local phone company. Your local phone company will have the names of your neighbors and in-city relatives (along with all other subscribers). When one of them dials you, your phone company looks up their number and then fills in the CID Name data. If your phone company is big and has their act together, you can sometimes get CID Name for calls placed from other cities that they serve, but usually this doesn't work across company boundaries.However, Citibank is almost certainly NOT using your phone company to handle their 800 number, so it won't be registered with your local carrier.The long form of this explanation is a little more complex, and there are more edge cases, and the realities of CID Name are slowly getting better, but this should suffice to explain why this happened to you this way....
