Boulder County's Marriage License Process, and Its One Real Catch

Boulder is the one Colorado county on our comparison list that skips the county-clerk counter entirely: no walk-in, no in-person appointment, just a video call. That sounds like the most convenient option for a couple flying in from abroad. It mostly is, but there’s a mailing-address catch that can genuinely derail your trip if you don’t plan around it.

The video appointment isn’t a remote option

Boulder’s application runs over Microsoft Teams, and per the county’s own instructions, both applicants must be “present, together in the same room, and in Colorado” for it. Worth being clear about what that does and doesn’t mean: it replaces the counter visit, not the travel. You can’t complete this from your home country before you fly; you still need to already be in Colorado, together, when you book and attend the call.

What to have ready for the appointment:

• Valid photo ID for both of you (passport, driver’s license, or certified birth certificate).
• Social Security numbers, or the affidavit described below if you don’t have one.
• Payment for the $30 license fee, by credit/debit card or e-check.
• Microsoft Teams installed beforehand, so you’re not troubleshooting software minutes before the call.

During the appointment, both of you sign the application electronically via an emailed link, with your IDs verified on camera.

The catch: it can only be mailed to a Colorado address

This is the part that catches international couples off guard. Boulder County does not mail an issued license outside Colorado, full stop. If neither of you has a Colorado mailing address, standard USPS delivery to your hotel isn’t a reliable option, and the county’s default process assumes you do.

The workaround exists, but it isn’t automatic: contact the Recording office directly to arrange same-day pickup, which the county’s own page frames as something specifically for out-of-state applicants. Don’t assume this happens by default just because you mentioned you’re visiting; call ahead and ask for it before your appointment, not after.

We haven't independently confirmed exactly how far in advance you need to request pickup, or whether it's available every day the office is open. Call Boulder County's Recording office directly (303-413-7770) to confirm before you build your appointment day around it.

If you don’t have a Social Security number

Boulder is one of the more accommodating counties on this specific point. If you don’t have an SSN, you complete a Sworn Statement Affidavit, and it’s signed virtually, during the same video appointment, not something you need to get notarized separately beforehand. See the SSN affidavit, explained for what that form is generally; Boulder’s remote signing is a genuine alternative to the in-person on-the-spot notarization some other counties (El Paso confirmed) offer at the counter instead.

What it costs

• License fee: $30, same as everywhere in Colorado.
• Card payment fee: $0.75 plus 2.26% of the total if you pay by credit or debit card, confirmed directly from Boulder County’s own fee disclosure. E-check avoids this.

After the video call

The license is mailed to you (or handed over at pickup, if you arranged that). You and your partner complete the certificate portion yourselves on your actual ceremony day, then return the signed document to the Recording office using the pre-addressed envelope Boulder provides, or a county drop box. The county doesn’t publish an exact turnaround for the initial mailing, but notes that returned, signed licenses are typically processed within about two weeks once received.

The practical takeaway

Boulder’s process is genuinely the easiest county-clerk interaction on our list if you already have a Colorado address to receive mail at, or you call ahead to arrange pickup. It becomes a real logistical problem if you assume “video appointment” means “remote” and only discover the Colorado-only mailing rule after your call is already booked. Confirm your receiving plan (a Colorado address, or a pickup arrangement) before you schedule the appointment, not after.
