Glacier National Park Conservancy Logo ( [link removed] ) Important! New USPS Rule ( [link removed] ) If you were planning to make a donation before the
end of the year, we want to make sure you're aware of this
mailing change to ensure that any of your year-end gifts are
processed exactly how you intended.

What Changed?

As of December 24, 2025, the USPS will apply the official
postmark at a regional processing center, not your local mailbox
or post office. That means if you drop a donation envelope in a
blue collection box, or even inside your local post office, it
could be days before the envelope is officially postmarked.

And that delay matters.

Why the Postmark Matters for Charitable Giving

According to IRS rules, a charitable donation is considered made
on the date it is mailed, but only if you have proof of that
date.

Previously, the postmark date served as that proof. But now,
since the postmark is applied later in the process, it may no
longer reflect when you actually mailed your donation.

To ensure your gift is recorded for the 2025 tax year, we
recommend:

💌 Mail early: Try to have your check in the mail by Friday,
December 26

💌 Visit your local post office in person. Don’t drop your
envelope in a mailbox or use a self-service kiosk.

💌 Request one of the following:
• A Postage Validation Imprint (PVI) from the USPS counter
• A manual postmark (hand-stamped by a USPS employee)
• Certified Mail or Registered Mail options that include a
dated receipt.
These are all considered valid ways to document the date you
mailed your gift.

💌 Give online: For immediate confirmation, you can make a secure
gift on our website ( [link removed] ) up until 11:59 pm
on December 31.

We want to make sure your generosity is recognized in the tax
year you intended. Here are some other tips to ensure your gift
counts for 2025. ( [link removed] )
