Below are 3 of the many Q/A's copy/pasted from that page..
Q: How can I reduce the amount of mail I receive from the NRA?
A: Simply email us at
membership@nrahq.org or dial 800-NRA-3888 and request to be placed on the "Do Not Promote" list. This will significantly reduce the amount of mail you receive without affecting important mailings, magazine service, or your membership renewal.
Q: I applied for membership online but I haven't heard anything. What's going on?
A: When you submitted your online application, did you receive an email receipt verification? If yes, everything is in order and your membership is in processing. If no, please email us at
membership@nrahq.org and we will be happy to verify your new membership. Please note that Spam filters can prevent you from receiving the email receipt verification.
Q: I just joined online, what is my NRA member number?
A: Simply email us at
membership@nrahq.org and include your full name along with your complete mailing address. Online transactions can take 3-5 days to post to our viewable records. Once the information has posted, we will email your NRA member number to you.
