Ally Financial is a major U.S. auto lender and the number 855-306-6998 is their private collections phone line, not a listed customer service number. If you are being called repeatedly, you're not alone; RoboKiller alone reports that nearly 1 million calls have been made from this number.
Here's what you need to know about Ally Financial, why they might be calling you, and what you can do about it.

Ally Financial's Calling Habits Are No Secret
These calls aren't going unnoticed. Ally has been sued multiple times for violating the TCPA through its calling practices. In one federal complaint, the plaintiff claimed that Ally called her cell phone "at least approximately 500 times" regarding an auto loan, despite four requests to cease calls over the course of more than a year.
In 2021, Ally agreed to settle a nationwide class action suit for $787.5 million regarding allegations that it violated state laws by failing to include all legally required information in its repossession notices.
Why Is Ally Calling You?
Auto Loans, Leases, and Deficiency Balances
Ally is an auto lender. In 2024, the company originated $39 billion in new consumer auto loans and had roughly 4 million auto finance customers. If you've financed or leased a vehicle through a dealership at any point, there's a pretty good chance that Ally owns your paper.
Calls from 855-306-6998 usually start once you're past due or sometimes when you're within days of missing a payment. One commenter on 800notes shared: "I do realize that my monthly payment was due yesterday. What I don't realize, is why can't they see that I have a scheduled payment from their website to them in 2 days when I get paid, and why I need to receive 500 phone calls in the interim?"
In some situations, Ally continues calling even after repossessing a vehicle, seeking payment on the deficiency balance — the difference between the auction sale price of the repossessed vehicle and the remaining balance owed.
Their Strategy Varies Depending on What They're Collecting
Ally collects directly (first-party collections) through a subsidiary called Ally Servicing before sending charged-off accounts to third-party debt collection agencies and law firms. If you answer a call from 855-306-6998, you'll be speaking with an Ally employee, not someone from an agency working on commission.
Their strategy can differ based on whether they're calling about an active loan that's a few days past due or a deficiency balance from a repossession. However, there's one constant: the volume of calls.
What People Are Saying About These Calls
Relentless Frequency and Dead Air
Far and away the most universal description of these calls across all the platforms is that they're extremely frequent. One commenter on 800notes said: "I realize that this is Ally Financial, but there's really no reason to call my phone THREE times within a 10 minute time frame while I'm at work just to leave a solid 20 seconds of silence on my voicemail."
Another commenter reported six calls in a single day despite being less than a month past due: "Ally Financial calls me daily from this number sometimes up to 6 times in one day. I'm only a month behind on my car payment."
Numerous consumers report answering the calls only to hear nothing on the other end. An 800notes commenter explained: "I keep getting calls 2 or 3 times a day and whenever Ally calls they always leave a message but not when they call from this number. If you actually answer the call you get dead silence and then the call ends."
This pattern of dead air is consistent with predictive dialing systems that dial more calls than customer service representatives are available to take.
Wrong Numbers and Workplace Disruptions
Several people report getting these calls despite no current or past relationship with Ally Financial. An EveryCaller commenter said: "They keep calling and asking for a person who doesn't live at this number and whom I've never heard of."
A commenter at CallerCenter, who works in a medical clinic, reported getting more than five calls in a single shift: "They call my place of employment which is a medical clinic. It is a nuisance and prevents me from giving good patient care." Another commenter documented nine calls to their closed business over a weekend, including one call that came in at 8:08 PM on a Sunday night.
What Ally Doesn't Want You to Know
Your Credit Report Is Their Leverage
When Ally reports a delinquency or collection account to the credit bureaus, it is presumed valid until proven otherwise. No one has to verify the debt before putting it on your credit report. The onus is on you to dispute any errors or unverifiable information, and most consumers never do.
A collections account or derogatory mark from an original creditor like Ally can remain on your credit report for up to seven years and affects your ability to qualify for everything from housing to employment to future credit. The listing itself is a leveraged tool meant to coerce you into feeling as though you have no choice but to pay.
Information Is a One-Way Street
If you speak with someone who calls from this number, remember that any information you provide them can be used to further their collection efforts. Confirming your identity, admitting the debt exists, or giving them your updated contact information gives them exactly what they need to keep calling (or to pursue the account more aggressively).
The information flow should go one way: from them to you. You have the right to request written validation of the debt, including the current balance and the original loan details. You don't have to give them anything in return over the phone.
Why You Shouldn't Pay or Call Them Back
The Payment Trap
When most of us see a collections call pop up on our caller ID, the first thing we want to do is figure out how to pay it off so the calls will stop. That's exactly what companies like Ally are counting on. When you make a payment on a debt, you can "re-age" the statute of limitations, giving the creditor a brand-new timeline to collect the full amount.
Making a payment also doesn't mean the account will be deleted from your credit report. A paid collections account can remain on your report as a derogatory mark for years. Instead, find out what's really on your report and whether the listing can stand up to a little scrutiny under the Fair Credit Reporting Act (FCRA).
The Hidden Risks of DIY Disputes
Some consumers try to dispute collections listings on their own by mailing letters to the credit bureaus. Although that's certainly possible, disputing your credit report requires understanding exactly what you're disputing, how to word your dispute, and what documentation you need to provide. A consumer dispute letter that's poorly worded can actually confirm to the credit bureau that the information is valid, making it even harder to get it removed later.
Professional credit report dispute companies understand the FCRA procedural technicalities, recognize what's likely an error, and can apply steady pressure across all three bureaus at the same time. The difference between a single letter and a well-orchestrated dispute campaign is often the difference between a dispute denial and a deletion.
Getting Ally Financial to Leave You Alone
Your Credit Report Is a Reconnaissance Tool
Before you do anything, get copies of your credit report from all three bureaus: Equifax, Experian, and TransUnion. Scan the reports carefully to see if you find any listings for Ally Financial and make a note of the account status, balance, and dates. Inconsistencies between what they're telling you on the phone and what's showing up on your report are precisely the kind of ammunition that makes disputes successful.
Your credit report isn't just a history. It's a reconnaissance tool. Every piece of information on it has to be accurate, timely, and verifiable according to federal law. If Ally Financial can't substantiate what it's reporting when you challenge it, the listing has to come off. Getting a credit report deletion without paying a debt isn't a loophole — it's a standard outcome when the creditor fails to meet its credit reporting obligations.
