ILR: Passport stamped but IO didn’t write normal Brp reference

[Enaycat]

Hi, recently got back from a trip to the EU and on arrival at Heathrow, had no problem going through, officer was fairly in a good mood etc but she stamped my passport as per usual (just with the date of entry NOT leave to enter stamp). The only thing is she didn’t write my biometric card reference on top of stamp as usually happens. Is it ok? Or should I worry about that detail. Could it be that she just forgot or it’s not obligatory to write those details on top of stamp. Also could that be a internal sign (code) for my next entry? If anyone has ilr and has some stamps without the respective BRP number written on top of it please shed some light.


Thanks in advance!

They usually write it but the stamp is enough
