So mailed my forms and fingerprints to the ATF, Card was charged yesterday which got me to thinking. On a paper Form 4 can you call and check on the status or do you just wait for it to show up in the mail one day? BTW this was a form 4 transfer in the same state so no dealer involved.

Yes, you can call BATF as often as you'd like. Just be prepared to not hear the answer you want for 6-12 months

What I did was call once shortly after all the SilencerShop work was done to confirm they had what they needed (aka pending). Then I left it alone for a few months until I got impatient and started calling every month or so until it was approved.

Look here for NFA Branch number

NFA Branch number: 304-616-4500

I always call about a month after my check clears just to make sure my form is "In process", then I try to forget about it.

Maybe I'm a bit paranoid, but if there were to be some problem, I'd like to know early rather than 8-9 months later.

ETA: This is because on my first Form 4 I did wait about 8 months to call only to be told they had nothing on file. After a near panic stricken call to my dealer, it was determined that they had transposed a character on the serial number, thus the reason there wasn't a match in the database. He got it straightened out, my can actually was in process, and my stamp actually came in just a few days later. But still.
