Where to mail a Montana 100th birthday certificate request

Mail your completed Centenarian Application Form to Tessa Bailly, Governor's Conference on Aging, PO Box 4210, Helena, MT 59604. This is a different program from Montana's general proclamation office (which no longer processes birthdays by mail): the Governor's Conference on Aging, run through the Department of Public Health and Human Services, gets a Montanan turning 100 a certificate signed by the Governor and a spot in that year's Centenarian booklet — and the form's own instructions say it can be mailed in, not just emailed.

Key facts

  • This is specifically a 100th-birthday (centenarian) program — it doesn't cover younger birthdays or wedding anniversaries the way some other states' general proclamation offices do.
  • The form's own instructions say to "email form to [email protected] or print and mail to Tessa Bailly" at the PO Box address — an explicit mail option, unlike Montana's separate general proclamation portal, which is online-only.
  • The information you submit (with your consent) may also appear in that year's printed Centenarian booklet, distributed at the Centenarian Luncheon during the Governor's Conference on Aging.
  • Even if the centenarian can't attend the luncheon, they (or their family) still receive a copy of the booklet.
  • PostPal prints your completed form and hands it to USPS the next business day for $5 flat, with a dated confirmation emailed to you.
