Just married in Idaho? Congratulations. Idaho gives newlyweds one of the easiest name changes in the country: your marriage certificate is your legal proof, and no court order is needed. Here is exactly how to do it, in order, with what it costs and how long it takes.
Which Names Can You Take in Idaho?
Start here, because Idaho is refreshingly generous. Your certified marriage certificate is the legal name-change document for a married name, so there is no court order needed. And it covers more than a plain last-name swap: Idaho’s DMV rule lets you take either spouse’s last name, move your maiden name into the middle position, or hyphenate both surnames (one hyphen), all on the marriage certificate. Social Security follows the same logic. The only time you need a district court petition is to change your first name, or to pick a name the marriage cannot support.
Step 1: Get Certified Copies of Your Marriage Certificate
Idaho has a money-saving quirk here. The cheapest source is the county recorder that issued your license: a certified copy of a current marriage is just $2 (for example in Ada, Blaine, Idaho, and Valley counties). Order from that same county, since another county will not hold your record. The alternative is the state Bureau of Vital Records, which charges $16 per copy and has no walk-in counter (order online or by mail only). Grab 2 certified copies, since Social Security and the DMV each want an original. Details: Idaho Vital Records.
Step 2: Update Social Security First
Social Security is free and the same in every state: complete form SS-5, show your certified marriage certificate, and your new card (same number) arrives in about 2 to 3 weeks. Do this first, because the Idaho DMV requires the Social Security update before it will change your license. Details: ssa.gov.
Idaho has only 7 Social Security field offices statewide, the fewest of any state we cover, so the nearest one may be a drive. Plan that trip:
| City | Address | ZIP | Phone | Mon-Fri |
|---|---|---|---|---|
| Boise | 1249 S Vinnell Way | 83709 | (855) 377-9316 | 9 AM-4 PM |
| Caldwell | 1118 S Kimball Ave | 83605 | (877) 836-1560 | 9 AM-4 PM |
| Coeur D’ Alene | 7400 N Mineral Dr | 83815 | (866) 931-2523 | 9 AM-4 PM |
| Idaho Falls | 2196 Channing Way | 83404 | (866) 253-0489 | 9 AM-4 PM |
| Lewiston | 1617 19th Ave | 83501 | (877) 405-9796 | 9 AM-4 PM |
| Pocatello | 861 Jefferson Ave | 83201 | (866) 643-3407 | 9 AM-4 PM |
| Twin Falls | 1437 Fillmore St | 83301 | (866) 748-2087 | 9 AM-4 PM |
Step 3: Change Your Idaho Driver’s License
Idaho driver’s licenses are issued through county DMV offices (run by the sheriff or assessor), so the exact documents and process can vary a little by county. Call your county office before you go.
Update Social Security first, then visit in person with a state-certified marriage certificate. A marriage name change is processed as a duplicate license, so the fee is $20, not a full new-license fee.
If your license happens to be due for renewal, you can renew at the same time instead and pay the renewal fee ($35 for a 4-year adult license, $60 for 8 years).
Step 4: Update Your Vehicle Title and Registration
Own a car? Update the title at your county assessor’s DMV office (or by mail to the Idaho Transportation Department):
| Item | Detail |
|---|---|
| Where | County assessor’s DMV office, or mail to ITD Vehicle Services, PO Box 34, Boise, ID 83707 |
| Forms | Duplicate Idaho Title Application (ITD 3367) plus a “One and the Same Statement” (ITD 3125) noting the marriage name change |
| Bring | Current title info, driver’s license, and certified marriage certificate |
| Fee | $14 replacement-title fee (plus registration fees) |
What an Idaho Name Change Costs and How Long It Takes
The honest math for a standard married name change in Idaho:
| Step | Idaho cost |
|---|---|
| Social Security card (SS-5) | Free |
| Certified marriage certificate copies | $2 each (county recorder) or $16 (state) |
| Driver’s license (duplicate) | $20 |
| Vehicle title (ITD 3367) | $14 (plus registration) |
Core out-of-pocket runs about $40 to $55 – less if you use the $2 county copies. A passport update adds more only if yours is more than a year old.
Time: your new Social Security card takes about 2 to 3 weeks. There is no Idaho deadline to rush the license, but do it before you need ID in your new name. With only 7 Social Security offices statewide, plan that trip early.
Idaho Marriage Certificate Offices
Order certified copies from the county recorder that issued your license (cheapest), or from the state:
| Source | What it issues | Fee |
|---|---|---|
| County recorder that issued the license (Ada, Blaine, Idaho, Valley, etc.) | Certified copies of current marriages | $2 each |
| State Bureau of Vital Records | Certified copies, 1947 to present (online or mail only) | $16 each |
Idaho State Taxes
Idaho has a state income tax, and it has its own step (it does not just follow Social Security). In the Taxpayer Access Point (TAP), choose More, then Manage Names and Addresses, open the Names tab, select your current legal name, choose Change this name, and upload your marriage document. (Do not confuse this with Manage My Profile, which only edits a display nickname.) Then give your employer an updated Idaho W-4 so your W-2 matches.
Licensed Professional? Update With DOPL
Most Idaho professions are licensed by the Division of Occupational and Professional Licenses (DOPL), and a name change is a free record update:
| Credential | What to do |
|---|---|
| Nursing (RN/LPN) | No fee. In DOPL Online Services, go to More, then Names and Addresses, and submit the name change with a certified copy of your marriage license (also complete the Board of Nursing notarized Affidavit for Change of Name and bring an updated state ID). |
| Other DOPL professions | Real estate, cosmetology, and the rest: submit your board’s name-change request through DOPL Online Services with the certified marriage certificate; most are a free update. |
Update Your Voter Registration
Update your registration at VoteIdaho.gov (online, at least 11 days before an election) or by mailing the form to your county clerk. Idaho is voter-friendly: you can also register or update in person during early voting or right at the polls on Election Day. Do this once your Idaho ID shows the new name.
Idaho Name Change Mistakes to Avoid
A few Idaho-specific trip-ups: first, do not pay the state’s $16 per copy when the county recorder that issued your license sells the same certified copy for $2. Second, remember the DMV is county-run, so documents and process vary a little by county, and there is no walk-in vital-records counter, so order marriage copies ahead. Third, do not skip Social Security, which the DMV requires first. And fourth, do not assume your state tax account updates itself, since Idaho has a separate TAP step beyond the Social Security update. The good news: taking your spouse’s surname, moving your maiden name to the middle, or hyphenating are all allowed on the marriage certificate with no court.
Other Idaho Licenses to Update
A few state-issued credentials need your new name too:
- Firearm carry. Idaho has permitless (constitutional) carry, so no permit is required. If you hold a standard or Enhanced Concealed Weapons License (issued by your county sheriff), it does not update automatically: change your driver’s license first, then ask the issuing sheriff for a name-change or duplicate license. The fee is commonly about $15 but varies by county.
- Hunting and fishing. Update your name in your Idaho Fish and Game account (Go Outdoors Idaho).
- Passport. Federal and optional: use form DS-5504 (free within a year of issue) or DS-82; worth it if you travel.
Changing your name is one of the happiest kinds of paperwork there is. Take it one step at a time, in the order above, and you will be signing your new Idaho name before you know it.
