Frequently Asked Questions

Where can I find my USPS not-for-profit authorization number?

The USPS not-for-profit authorization number is usually a 6-digit number. It is different than your permit number. If you aren't familiar with your USPS not-for-profit authorization number, your mailing department should be able to provide it to you.

Can I get a sample with my artwork?

  • We'd be happy to produce a sample using your artwork!
  • Choose the specs for the product you are considering and send us your finished artwork
  • Files can be large. It will usually work best to send files via DropBox, WeTransfer or some other file sharing service. Or, you can upload to our site.
  • It will usually take about a week for us to produce the samples
  • Our sticker postcard mailers come with a raised spot UV layer giving the stickers a tactile enhancement you can see and feel! Here are the instructions for adding a foil or spot UV layer.
  • If you need help with the design, we can have one of our designers work on this for you. A $50 design fee will apply. Contact us for details.
  • Additional questions, send an email [email protected] or call us at 800.788.8633.

Can we use our not-for-profit indicia?

We can mail these either under our not-for-profit indicia (we'll invoice you for postage), or your indicia (USPS will deduct funds from your account when the mailing drops). Postage is roughly the same for either option.

Is there an additional charge for Truly Engaging to handle the mailing?

Our pricing includes the postcard and preparation needed for mailing. Postage is NOT included. It will cost you less for us to handle the mailing, as there are no shipping charges. Plus, your mailing department won't need to take care of your mailing, saving them time and resources for other projects.
