How to Transfer
Brokerage Accounts (ACATS)

The standardized account transfer system

ACATS (Automated Customer Account Transfer Service) is the system that transfers customer accounts between US brokerage firms. Governed by FINRA Rule 11870, ACATS establishes mandatory timelines, documentation requirements, and rejection procedures that all NSCC-member firms must follow. The National Securities Clearing Corporation (NSCC) processes ACATS transfers, handling an estimated 3–5 million account transfers annually.

The fundamental rule: the receiving firm initiates the transfer. You never need to call your old broker to 'release' your account. Under FINRA Rule 11870, the carrying firm is obligated to validate the transfer within 1 business day and complete delivery within 3 business days after validation.

From initiation to settlement

What you need before initiating

The minimum requirement is just your account number at the delivering firm and a signed TIF. But providing a recent statement accelerates validation by giving the receiving firm reference data for positions, titles, and account type matching — the three most common rejection points.

Every reason ACATS can reject — mapped to FINRA Rule 11870(d)(3)

Under FINRA Rule 11870(d)(3), the carrying firm may only reject a transfer for specific, enumerated reasons. Here are the rejection codes and how to resolve each:

The three most common rejection reasons: title mismatch (Code 01), SSN mismatch (Code 02), and margin debit (Code 06). All three are preventable. Before initiating, verify your name is spelled identically at both firms, your SSN is correct, and any margin balance is paid off.

When to use each type

A full ACATS transfer moves everything — all securities, options, cash, and mutual funds. A partial transfer ('specifically designated' under FINRA Rule 11870) moves only the assets you specify. Both follow the same ACATS timeline.

For concentrated stock holders planning to contribute shares to an Embark SPV, a partial ACATS transfer — or better, a direct DTC delivery — is typically more appropriate than a full account transfer. You're moving a specific position to a specific structure, not relocating your entire investment life.

Assets that require alternative handling

ACATS transfers most standard securities, but certain asset types are explicitly excluded or subject to delayed delivery. Understanding what can't move helps you plan ahead and avoid forced liquidations.

Frequently Asked Questions

Can I trade during an ACATS transfer?

No. Once the carrying firm validates the ACATS transfer, your account is frozen. All open orders are cancelled — with one exception: options expiring within 7 business days of the validation date remain active. You cannot place new trades, withdraw cash, or make any changes to the account during the transfer. This is why timing matters. If you have pending trades or need to make adjustments, complete them before the transfer is initiated. The freeze typically lasts 3–5 business days.

What if my ACATS transfer is rejected?

If the carrying firm rejects the transfer, the receiving firm will notify you of the rejection code (see the 10 codes in FINRA Rule 11870(d)(3)). Fix the underlying issue — update your name, provide the correct account number, resolve the margin balance — and then re-initiate. The re-submitted request goes through the same 1-day validation + 3-day delivery cycle. Resolution for most rejected transfers takes 1–3 weeks total, including diagnosis and re-submission. If the carrying firm improperly rejects or delays, you can file a complaint with FINRA.

How long does an ACATS transfer take for retirement accounts?

The same FINRA Rule 11870 timelines apply: 1 business day for validation, 3 business days for delivery. However, retirement accounts (IRA, 401(k) rollovers) often require additional documentation — successor custodian acceptance, rollover paperwork — that can add 1–3 business days to the preparation phase. The transfer itself is no slower, but the setup takes longer. Ensure the receiving firm is designated as the successor custodian before initiating to avoid delays.

Is there a fee for ACATS transfers?

The delivering brokerage may charge an account transfer fee, typically $50–$75 per account. Major brokerages including Fidelity, Schwab, and Vanguard often charge this fee. Many receiving brokerages will reimburse the transfer fee if you transfer above a certain asset threshold — commonly $25,000 or more. Ask the receiving firm about reimbursement before initiating. Some discount brokerages have eliminated outgoing transfer fees entirely. The fee, if charged, applies to the ACATS transfer itself — DTC deliveries of individual positions typically do not incur this fee.
