What Is 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.
Step-by-Step Process
From initiation to settlement
Preparation
Gather account number + recent statement from delivering firm. Resolve any margin balance. Close open orders.
Initiation
Open account at receiving firm (if needed). Sign Transfer Instruction Form (TIF). Specify full or partial transfer.
Validation
Carrying firm validates within 1 business day. Account is frozen. Open orders cancelled (except options expiring within 7 days).
Delivery
Assets delivered within 3 business days post-validation. Securities move via DTC; cash via Fedwire.
Settlement
All transferable assets settled at receiving firm. Cost basis data transferred via CBRS.
Residuals
Residual credits (pending dividends, interest) transferred within 10 business days after accrual.
Required Documents
What you need before initiating
Account number at the delivering brokerage
Most recent account statement (for verification)
Transfer Instruction Form (TIF) — provided by receiving firm, signed by all account holders
For retirement accounts: successor custodian/trustee acceptance authorization
For joint accounts: signatures of ALL account holders
Government-issued ID (some receiving firms require for new accounts)
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.

Rejection Codes
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:
| Code | Reason | Resolution |
|---|---|---|
| 01 | Account title mismatch | Ensure names match exactly at both firms |
| 02 | SSN/Tax ID mismatch | Update SSN at delivering or receiving firm |
| 03 | Account type mismatch | Match account types (cash vs margin, individual vs joint) |
| 04 | Invalid account number | Verify account number with delivering firm statement |
| 05 | Duplicate request | Cancel prior request before resubmitting |
| 06 | Account frozen / credit violation | Resolve margin debit or regulatory hold first |
| 07 | Missing authorization | Ensure all account holders signed the TIF |
| 08 | Additional docs required | Provide death certificate, legal name change docs, etc. |
| 09 | Customer rescinded | Re-initiate if still desired |
| 10 | Flat account (no assets) | Verify correct account number; fund if needed |
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.
Full vs Partial Transfers
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.
Use Full Transfer When
- You're completely leaving the delivering brokerage
- You want all positions, cash, and history in one place
- You don't need to maintain any accounts at the old firm
Use Partial Transfer When
- You want to keep some assets at the delivering firm
- You only need to move specific positions (e.g., concentrated stock)
- You have nontransferable assets you want to manage separately
- You want to avoid freezing the entire account
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.
What ACATS Can't Move
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.
| Asset Type | ACATS Status |
|---|---|
| US-listed stocks, ETFs, bonds | Fully transferable |
| Options | Transferable (OCC-cleared) |
| Mutual funds | Transferable IF receiving firm has distribution agreement |
| Cash balances | Fully transferable |
| Proprietary funds/money markets | NOT transferable — must be liquidated |
| Fractional shares | NOT transferable — liquidated to cash |
| Cryptocurrency | NOT transferable via ACATS |
| Limited partnerships (retail) | NOT transferable via ACATS |
| Annuities | Delayed delivery — may take 30+ days |
| Foreign securities (no CUSIP) | Delayed delivery — up to 30 days |
Forced Liquidation Tax Impact: When the delivering brokerage liquidates nontransferable assets, those sales are taxable events. The 1099-B will reflect the sale at current market value. If you hold positions with large unrealized gains that can't transfer, plan the timing carefully — consider selling before the transfer to control lot selection, or wait and sell separately.
FAQ
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.
