What this letter asks of you, what to gather, and what to ask a professional if you need one. No phone number asked.
A statutory Notice of Deficiency: the IRS found your income tax needs to be adjusted because information it received from others, like your employer or bank, does not match your return. It is a proposed change, not a bill or an audit.
The IRS matched your return against W-2s, 1099s and other forms it received and found a difference.
The IRS page describes two paths, one if you agree with the change and one if you do not. The response form that came with your letter is where you mark which one applies.
If the IRS does not hear from you and you do not file a Tax Court petition, it will assess the proposed changes and send a bill; interest accrues and penalties may apply.
If someone used your name and Social Security number to file, the IRS page directs you to Form 14039, Identity Theft Affidavit.
Check the notice number against the official IRS site before you respond, and respond only to the address or number printed on the official page.

Not always. Upload the letter and the free report explains what it asks for and what to gather; if a professional makes sense, the report says why and what to ask. TaxScout never shares your request with any firm unless you ask for that on the report.

TaxScout lists CPAs, EAs and tax preparers from public IRS records. You choose whom to contact; nothing about your letter is shared with any firm unless you ask for that on your report.
Not tax advice. TaxScout is not the IRS. Deadlines and steps above are quoted from the IRS page linked at the top and may change; the letter in your hand controls.
