| I've signed quite a few of these being a civil servant, and I've never had the passport agency phone me, then again, they can look me up as with maybe Andy through your employer. Worth noting tho, the listed people also do need a passport themselves.
I know Hampshire Police (neighbour is a policeman) don't allow their staff to sign these, as my needed renewal last year, in the end, I got my boss to do it. |
