What is AOS-058?
AOS-058: Request for Change of Address is a one-page card from the San Bernardino County Assessor-Recorder-County Clerk that an owner returns to the San Bernardino County Assessor when the address on an attached tax bill or letter is not correct, giving the correct mailing address instead.
The printed text sets the rules for the card. It is returned only when the address is wrong, and a separate card is completed for each parcel. The card asks for the parcel number, the new mailing address, the city, state and ZIP code, and a daytime and an evening telephone number. The person completing it prints their name, which must be the owner of record, then signs and dates it.
The back of the card is a ready-to-mail panel. It is pre-addressed to the San Bernardino County Assessor's Office, with a space for a first class stamp. The revision printed on the form is AOS 058 Rev. (01-25).
On the county's list of forms and fees, AOS-058 appears under the Assessor, alongside other Assessor forms such as the Homeowners' Exemption Claim (BOE-266) and the Preliminary Change of Ownership Report (BOE-502-A). Those forms serve different purposes; AOS-058 only corrects the mailing address.
Who needs to file AOS-058?
The owner of record of a parcel in San Bernardino County uses AOS-058 when the address printed on the tax bill or letter attached to the card is not correct. The card says the name printed on it must be that of the owner of record.
- One card per parcel. If you own several parcels with a wrong address, complete a separate card for each parcel.
- Exclusion. Do not return the card if the address on the bill or letter is correct.
The card gives no instructions for representatives, agents or anyone signing on behalf of an owner, and it asks the person who prints their name to sign. The county lists a separate form on its forms page, AEO-011: Agent Authorization, under the Assessor, but the card does not refer to it. Contact the Assessor's Office if someone other than the owner needs to submit the change.
When to file AOS-058
Return AOS-058 when you notice that the address on the tax bill or letter attached to the card is wrong. The card prints no due date. Its only timing guidance is that all areas should be completed and the card signed, to avoid a possible delay in processing the request.
If the address on the bill or letter is correct, there is nothing to file: the card says not to return it. For several parcels with incorrect addresses, complete and return one card per parcel. The card does not state a processing time.
How to fill out AOS-058
Confirm the address is wrong
Check the address on the attached tax bill or letter. Complete the card only if it is not correct; if it is correct, do not return the card.

How to submit AOS-058
AOS-058 is returned by mail to the Assessor. The card itself is the return piece: it carries a first class stamp box and the Assessor's Office address.
- By mail: place a first class stamp on the card and send it to: San Bernardino County Assessor's Office, 222 W. Hospitality Lane, 4th Floor, San Bernardino, CA 92415-0311. The address block is printed under Josie Gonzales, Assessor-Recorder-County Clerk.
The card names no online portal, in-person option or fee. Before mailing, check that every area is completed and the card is signed, since the form warns that an incomplete or unsigned card may delay processing. Send a separate card for each parcel. FillingPDF lets you fill out and download the PDF; submission follows the channel above.
Common mistakes to avoid
- Returning the card when the address on the tax bill or letter is already correct; the form says not to return it in that case.
- Using one card for several parcels instead of completing a separate card for each parcel.
- Printing a name that is not the owner of record; the form requires the printed name to be the owner of record.
- Mailing the card unsigned or undated; the form warns that incomplete or unsigned cards may delay processing.
- Leaving the Parcel No., the city, state and ZIP code or the telephone lines blank when the form asks that all areas be completed.
- Sending the card to a different office instead of the San Bernardino County Assessor's Office, 222 W. Hospitality Lane, 4th Floor, San Bernardino, CA 92415-0311.
- Mailing the card without a first class stamp in the space the form marks for it.
