Required Documents

What Do You Need to Port Your Phone Numbers?

Gather these items before starting the porting process. Missing information is the #1 cause of delays.

Customer Service Record (CSR)

A CSR is a document from your current carrier showing your account details. It contains the exact information needed for porting.

How to get it: Call your current provider and request a "CSR" or "Customer Service Record." AT&T, Comcast, and most carriers provide this free within 1-2 business days.

What it shows: Account number, authorized name, service address, phone numbers on account, BTN (Billing Telephone Number).

Letter of Authorization (LOA)

An LOA authorizes VoipPlus to port your numbers away from your current provider. It must be signed by an authorized account holder.

We provide the form: VoipPlus will send you the LOA to sign. It's a simple one-page document.

Important: The name on the LOA must match the name on your current account exactly. "John Smith" vs "John A. Smith" can cause rejections.

Recent Phone Bill

A copy of your most recent phone bill helps verify account information and identify all numbers to be ported.

What we look for: Account number, service address, list of phone numbers, account holder name.

Tip: If your bill doesn't list all DIDs (direct numbers), request a DID inventory from your current provider.

List of Numbers to Port

Provide a complete list of every phone number you want to transfer. Don't forget fax lines, direct lines, and toll-free numbers.

Include: Main number, fax number, direct DIDs, toll-free numbers, any additional lines.

Partial ports: You can port some numbers and leave others with your current provider if needed (e.g., keeping a fax line temporarily).

Timeline

How Long Does Number Porting Take?

Porting time depends on your current carrier. Here are typical timelines for Chicago-area providers.

Current Carrier Typical Timeline Notes
AT&T (Landline/PRI) 7-14 business days Requires CSR. May need contract buyout.
AT&T (U-verse) 5-10 business days Usually straightforward.
Comcast Business 10-15 business days Check for ETF (early termination fees).
RingCentral 5-10 business days Request PIN from RC before starting.
Vonage Business 5-10 business days Usually straightforward.
8x8 5-10 business days Request port-out PIN first.
Nextiva 5-10 business days May require cancellation notice first.
Other VoIP Providers 5-10 business days VoIP-to-VoIP ports are typically faster.
Toll-Free Numbers 3-7 business days Toll-free ports separately from local.

The Process

How Does the Porting Process Work?

Here's what happens from start to finish when you port your numbers to VoipPlus.

1

Gather Documents

Collect your CSR, recent bill, and list of numbers. Request CSR from current provider if you don't have one.

2

Submit LOA

Sign and return the Letter of Authorization. VoipPlus submits the port request to your current carrier.

3

FOC Date

Carrier confirms the port and provides a Firm Order Confirmation (FOC) date—the day numbers will transfer.

4

Cutover

On FOC date, numbers switch to VoipPlus. We monitor the cutover to ensure calls route correctly.

Avoid Delays

What Can Delay a Number Port?

These issues cause most porting rejections. Avoid them for a smooth transfer.

Name Mismatch

The name on your LOA must exactly match your current account. "ABC Company" vs "ABC Company LLC" will cause rejection.

Solution: Use your CSR to verify exact account name.

Address Mismatch

Service address must match exactly. "123 Main St" vs "123 Main Street" or missing suite numbers cause rejections.

Solution: Copy address exactly from your bill or CSR.

Wrong Account Number

Account numbers on bills can be formatted differently than what carriers have on file. PRI accounts may have separate BTN.

Solution: Get CSR to confirm account number format.

Account PIN Required

Some VoIP providers (RingCentral, 8x8) require a port-out PIN that you must request before porting.

Solution: Call current provider and request port-out PIN before starting.

Contract/ETF

Early Termination Fees (ETF) don't stop porting, but your old carrier may bill you. Know your contract status.

Solution: Review contract terms. Often savings from VoIP offset ETF quickly.

Account Freeze/Suspension

Accounts with past-due balances or fraud flags can't be ported until resolved.

Solution: Bring account current before porting.

Common Questions

Number Porting FAQ

Will there be downtime during the port?

Porting is designed to be seamless. There's typically a brief moment (seconds to minutes) when calls route to the new system. We can arrange temporary forwarding if needed for zero-downtime transitions.

Do I need to cancel my old service?

No. Porting automatically releases your numbers from the old carrier. Your old service will be canceled (or reduced) once the port completes. Don't cancel before porting—you'll lose your numbers.

Can I port just some of my numbers?

Yes. Partial ports are allowed. You can port your main number to VoipPlus while keeping a fax line with your current provider, for example.

What about toll-free numbers?

Toll-free numbers (800, 888, 877, etc.) port separately from local numbers but follow a similar process. They typically port faster (3-7 days) since they're handled by a different system (RespOrg).

Is there a charge for porting?

VoipPlus does not charge porting fees. Your old carrier may charge an early termination fee if you're under contract, but they cannot charge for the port itself (it's your legal right to port numbers).

Can my old carrier block the port?

Carriers cannot refuse a valid port request (it's FCC regulated). They can reject for information mismatches, but once corrected, the port must proceed. "Slamming" (unauthorized porting) is illegal, but authorized porting is your right.
