Well , I hope you're talking about the generic stickers like tire pressure.
If they hit your drivers door , which I'm assuming is what your talking about , you can NOT replace the decal with the build date and VIN number.
They are "factory installed only".
I've been in the body/paint biz for 20 years and have never been able to get one , even for a brand new car with 5 (yes , five) miles on it and STILL owned by the dealership. We had a car roll back from the transporter and destroy the door (GM/Chevy) , they are absolutely not available. Too many possibilities for use in vehicle theft and VIN switching , they don't sell them or allow them out. 1 per car and thats it. I've done many rebuilders that were perfectly legitimately destroyed , you can't get them for any reason.
What I've always done in the past if someone "has" to have it , is to cut out the whole area around the sticker (as far as possible in all directions) and slowly weld it one tack at a time back into the new door and mask it off refinish around it , or belnd up to it.
It's the only way.
