TL;DR
- File your USPS change of address online at least a few days before move day. Standard forwarding runs 12 months, and it does not catch everything.
- California requires you to notify the DMV of a new address within 10 days, even if you are not getting a new license.
- USPS forwarding is a bridge, not a fix. Banks, the IRS, and some subscription services never honor it. Update those directly.
- Utilities in San Diego County are not one account. SDG&E covers gas and electric almost everywhere, but water, sewer, and trash depend on which of the 67 cities you are in.
- Use the checklist table below to work through government, financial, home, and everyday accounts in one pass instead of remembering them as they come up.
Filing your change of address takes ten minutes on usps.com and forwards most mail for 12 months, but it will not update your driver’s license, your bank, or your water bill. Those need to be changed one by one, and the list is longer than most people expect.
Master Movers San Diego walks clients through this same list on every local move. Below is the full version: what USPS forwarding actually covers, what California requires by law, and every account category people forget until a bill goes to the wrong house.
What does USPS mail forwarding actually cover, and what does it miss?
USPS forwarding covers standard first-class mail, most magazines, and packages sent through the Postal Service for 12 months from your move date. Premium Forwarding Service can extend that if you need it.
It does not reliably cover everything. Some banks, government agencies, and subscription billers use their own address records and never check USPS forwarding at all. A card reissue from your bank can still go to the old address even with forwarding active. Certified mail and some legal notices are also inconsistent.
Treat forwarding as a safety net for the mail you forgot to redirect, not a substitute for updating your address everywhere that matters. File it at usps.com/move, or in person at any San Diego post office, at least a few days before your move date so it activates close to when you need it.
Does the California DMV require a separate address update?
Yes. Under California law, residents must notify the DMV of a new address within 10 days of moving, whether or not you are getting a new license or registering a new car. This is separate from USPS forwarding and separate from the 20 days new California residents get to obtain a license after establishing residency. If you are relocating to San Diego from another state, our moving to San Diego relocation guide covers the rest of what new residents need to handle in that first month.
Update it online at dmv.ca.gov for both your driver’s license and your vehicle registration. If your registration renewal or a citation notice goes to your old address because you skipped this step, that is on you, not the DMV.
Who do you actually need to notify when you move in San Diego?
Work through this by category instead of trying to remember everything at once. The government and financial accounts matter most because they carry legal or credit consequences if they lag.
| Category | Update these | When |
|---|---|---|
| Government | USPS, DMV (license + registration), voter registration, IRS (Form 8822), Social Security if applicable | Before move day for USPS; within 10 days for DMV |
| Financial | Banks, credit cards, student loans, mortgage or landlord, insurance (auto, home or renters, health) | Before move day |
| Home and utilities | SDG&E, water/sewer/trash for your city, internet and cable, HOA or property manager | 1 to 2 weeks before |
| Everyday accounts | Employer payroll and HR, doctors and dentist, kids’ school, Amazon and other retailers, subscriptions and streaming | First 2 weeks after |
| Local specifics | Gym membership, place of worship, pet microchip registry, vehicle toll account (FasTrak) | First month after |
San Diego County’s utility setup trips people up because it is not one company. SDG&E handles gas and electric across almost the entire county, but water, sewer, and trash billing runs through whichever of the 67 cities you are moving into or the county for unincorporated areas. Check your new city’s utility page as soon as you have an address, not on move week.
What’s the smartest order to update everything?
Start with USPS and the accounts that cause real problems if they lag: banks, insurance, and your employer’s payroll department. A paycheck or an insurance card mailed to your old address is the kind of miss that actually costs money.
Handle the DMV within its 10-day window so you are not carrying an expired address on your license. Then work down through utilities, healthcare, and school before finishing with the everyday accounts, subscriptions, and memberships that matter less if they take an extra week.
If you are also working through the rest of the move, our moving checklist and timeline for San Diego folds this into the full week-by-week plan, including HOA paperwork and parking permits.
Frequently asked questions
How long does USPS mail forwarding last?
Standard forwarding runs 12 months from your move date. After that, mail addressed to your old home gets returned to sender instead of forwarded, so anything still going to the old address needs to be fixed directly before the year is up.
Do I need to update my address with the DMV if I am not getting a new license?
Yes. California requires an address update within 10 days of moving regardless of whether you need a new license or are just updating your record. You can do it online at dmv.ca.gov.
Can I file a change of address before I actually move?
Yes, and it is the better move. File a few days ahead with a start date matching your move day so forwarding activates close to when you need it, instead of leaving a gap where mail sits at the old address.
Does change of address forwarding cover packages from Amazon and other retailers?
Sometimes, but not reliably. Retailers often use their own saved address on file rather than checking USPS forwarding. Update your address directly in your Amazon and other retail accounts instead of counting on forwarding to catch it.
Which utility do I contact for water and trash in San Diego County?
It depends on the city. SDG&E covers gas and electric for nearly the whole county, but water, sewer, and trash are billed by your specific city or, in unincorporated areas, the county. Look up your new city’s utility billing page as soon as you have a move-in address.
What happens if I forget to update my address somewhere?
Most misses just mean a delayed bill or statement, which USPS forwarding usually catches for the first 12 months. The real risk is government accounts like the DMV, where an outdated address can mean a missed registration renewal or citation notice you never see.
