AB 1610 directs county elections officials to send forwardable, postage-paid address-confirmation notices when the county receives change-of-address data from the U.S. Postal Service or its licensees, or through programs such as NCOA or Operation Mail. The bill prescribes two notice templates depending on whether a voter’s residence or mailing address changed, requires written confirmation for address changes, and ties whether a voter’s registration becomes inactive to the type of notice sent.
This is procedural but consequential: it imposes specific mailing formats and record updates on counties, creates a bright-line rule about when to set a registration inactive, and embeds a 15-day-before-election practical deadline that can push voters toward provisional ballots if they don’t respond in time. Compliance officers and county election administrators should weigh implementation costs, data-quality risks from postal-change feeds, and voter-access implications.
At a Glance
What It Does
The bill requires counties to send forwardable, postage-paid address-confirmation notices using USPS change-of-address data and to update voter records when a new mailing address is provided. It prescribes two notice variants depending on whether the residence or mailing address changed and references the federal 52 U.S.C. 20507(d)(2) notice format for certain cases.
Who It Affects
County elections officials will implement the mailings and update registration databases; voters whose USPS records show moves — including those who move within California, out of state, or leave no forwarding address — are the direct targets. Vendors and vendors’ licensees that supply NCOA/Operation Mail data will feed the process.
Why It Matters
The bill replaces discretionary practices with specific templates and status rules, reducing local variation but shifting operational burden (mailing logistics, data handling) to counties and creating a sharper line between 'active' and 'inactive' registrations that can affect voter access close to an election.

What This Bill Actually Does
When counties receive USPS change-of-address data or information from licensees and address-update services, AB 1610 requires them to send a forwardable notice with a postage-paid, preaddressed return form so the voter can confirm or correct their address. If the change-of-address feed shows the voter moved and left no forwarding address, or moved out of state, the county must use a forwardable notice substantially like the one described in federal law (52 U.S.C. 20507(d)(2)).
For in-state moves or when a voter’s mailing address becomes invalid, the bill sets two notice templates: one that tells the voter their residence was updated, and another that tells them their mailing address was updated. Both templates instruct the voter to return the prepaid postcard or call a toll-free number if the update is wrong, and they warn the voter that they must notify the office at least 15 days before the next election to avoid being forced to use a provisional ballot.When a voter’s mailing address differs from their residence and the mailing address is no longer valid, counties must choose among three actions: (A) if a new mailing address appears, mail the forwardable notice to that new address and add it to the voter’s record; (B) if no new mailing address is provided but the voter can receive mail at their residence, send the notice to the residence and remove the invalid mailing address from the record; or (C) if no new mailing address is provided and the voter cannot receive mail at their residence, send the federal-format forwardable notice referenced above.
The bill also makes the use of a toll-free number optional and requires any actual change to a voter’s address to be received in writing.Finally, AB 1610 ties record status to the notice type: mailing the forwardable address-confirmation notice that corresponds to in-state/mailing-address updates prevents the county from marking the registration inactive, while mailing the federal-style notice for nonforwardable or out-of-state cases requires the county to mark the registration inactive. That status change affects how the voter will be treated in subsequent elections unless they respond to the confirmation.
The Five Things You Need to Know
The bill requires forwardable notices to include a postage-paid, preaddressed return form for voters to confirm or correct address information.
Counties must use one of two prescribed notice templates depending on whether a voter’s residence or mailing address changed, and both warn about a 15-day-before-election deadline for avoiding provisional ballots.
If a new mailing address is available, the county must add it to the voter’s record and send the forwardable notice to that new mailing address.
If no forwarding address is available and the county sends the federal-style notice (per 52 U.S.C. 20507(d)(2)) the voter’s registration must be updated to inactive; other forwardable notices prevent an inactive designation.
Any change to a voter’s address must be received in writing; using a toll-free phone number to confirm an old address is optional.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Triggering notices from USPS and third‑party address feeds
This section makes USPS change-of-address data and similar feeds the explicit triggers for sending forwardable address-confirmation mail. It instructs counties to send a forwardable notice with a postage-paid return form and, when the data show no forwarding address or an out-of-state move, to default to the federal-format confirmation notice. Practically, this ties county workflows to the cadence and accuracy of postal feeds and to whichever licensees supply that data.
Two required notice templates for in-state or invalid mailing updates
AB 1610 prescribes two substantially fixed message forms: one stating the residence address was updated, the other saying the mailing address was updated. Both inform voters that no action is necessary if the update is correct, but require written correction (postcard or call) if incorrect and flag the 15‑day pre‑election cutoff. Standardized wording reduces local variation but locks counties into a specific voter-facing script.
How to handle cases where mailing and residence addresses differ
When a voter’s mailing address differs from their residence and the mailing address becomes invalid, counties must follow a three‑path rule: add and send notice to a new mailing address if available (A); if no new mailing address and the residence can receive mail, send notice to residence and remove the invalid mailing address (B); if no new mailing address and the residence cannot receive mail, send the federal-format notice (C). Each path creates a distinct database action (add, remove, or federal notice) that directly alters how the voter will be contacted and whether their mailing field remains populated.
Nonforwardable mailings and out‑of‑state moves
If change-of-address data come from a nonforwardable mailing and show a move with no forwarding address or an out‑of‑state move, the county must send the federal-style forwardable notice aligned with 52 U.S.C. 20507(d)(2). That references a federal confirmation form used in federal voter-roll maintenance and signals that such cases require a more formal confirmation process and different downstream status handling.
Optional toll‑free confirmation and written-change requirement
The bill clarifies that offering a toll-free number to confirm an old residence is optional, but it makes a written submission the required vehicle for any actual change to a voter’s address. This limits the set of acceptable change mechanisms to written communications (including the prepaid postcard), which simplifies recordkeeping but excludes purely oral or electronic-only corrections as the basis for a change.
When to mark a registration inactive
AB 1610 draws a bright line: mailing the forwardable confirmation notice described in (b)(1) prevents the county from changing the voter’s status to inactive, whereas sending the federal-style notice in (c) or (b)(2)(C) requires the county to mark the registration inactive. This creates an operational step that directly ties the type of mailed notice to the voter’s status in the rolls and therefore to how they will receive ballots in future elections.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Voters who move within California — they receive a prepaid, easy way to confirm or correct their registration and avoid inadvertent disenfranchisement if they respond.
- County election administrators — they get a standardized, legislated workflow and prescribed notice language that reduces local ambiguity about how to handle USPS change feeds.
- Statewide compliance functions and legal teams — the bill aligns certain practices with the federal 52 U.S.C. 20507(d)(2) format, helping counties meet federal confirmation standards in out-of-state or no-forwarding-address cases.
Who Bears the Cost
- County election offices — increased mailing volume, processing of returned postcards, database updates to add/remove mailing addresses, and staff time to implement the three-path handling will raise operational costs.
- Voters in areas with unreliable mail delivery — those who cannot reliably receive mail at their residence may be pushed into the federal confirmation pathway and have their registration marked inactive unless they respond.
- Vendors and data providers — vendors supplying NCOA/Operation Mail data may face more detailed integration and quality-control demands from counties relying on their feeds for official roll maintenance.
Key Issues
The Core Tension
The bill trades uniformity and roll accuracy for potential voter friction: it tightens procedures (standard templates, written-change requirement, and explicit inactive triggers) to improve the cleanliness of voter rolls, but those same rules — coupled with ambiguity about mailability and reliance on postal feeds — risk misclassifying voters and increasing provisional voting or inactive status for people who never intended to sever their registration.
AB 1610 fixes process points but leaves several implementation gaps that carry real risk. The bill hinges on the phrase "area where the voter can receive mail," but it does not define what qualifies as able-to-receive-mail; counties will need policy guidance to decide whether P.O. boxes, gated communities, or multi-unit buildings count.
That ambiguity affects the choice among the three paths for handling an invalid mailing address and therefore whether a voter’s mailing field is removed or their registration becomes inactive.
The reliance on USPS change-of-address feeds and licensee-provided NCOA/Operation Mail data introduces accuracy and timing problems. Postal feeds can reflect temporary moves, household-level forwarding, or commercial updating services that misattribute changes; the bill does not specify minimum data quality checks or reconciliation procedures.
Also, the written-only requirement for address changes (with an optional toll-free phone confirmation) reduces ambiguous verbal updates but may create barriers for voters who lack access to mail, cannot complete a paper postcard quickly, or expect digital correction options.
Operationally, counties will face upfront mailing costs, system changes to add/remove mailing addresses automatically, and a need to train staff on when to set registrations inactive. The 15-day pre-election deadline in the notice creates a hard practical consequence — voters who miss that window risk provisional ballots — but the bill does not provide any interim remedies or expedited processes for late confirmations, nor does it allocate funding for the increased administrative workload.
