This document announces that, on May 13, 2021, OMB approved, for a period of three years, the information collection requirements relating to the caller ID identification rules contained in the Commission's Order, FCC 20-136, published at 85 FR 73360 on November 17, 2020 (47 CFR 64.6303(b), 64.6305(b) and (c), and 64.6306(e)). The OMB Control Number is 3060-1285. The Commission publishes this document as an announcement of the effective date of §§ 64.6303(b) and 64.6305(b) and (c). In the Order and the text of §§ 64.6305(b) and (c) and 64.6306(e), the Commission directed the Wireline Competition Bureau to set the compliance dates for these rules. On April 20, 2021, the Wireline Competition Bureau released a Public Notice, DA 21-454, setting the date by which voice service providers submit information into the Commission's Robocall Mitigation Database (database) (§ 64.6305(b)) and the date by which intermediate providers may no longer accept voice traffic from any provider that does not appear in the database (§ 64.6305(c)). Voice service providers must submit information into the database by June 30, 2021 and intermediate providers may no longer accept voice traffic from any provider that does not appear in the database by September 28, 2021. We therefore modify the text of § 64.6305(b) and (c), previously published at 85 FR 73360, to incorporate these compliance dates announced by the Wireline Competition Bureau. The amendment to § 64.6306(e), published at 85 FR 73360 on November 17, 2020, remains delayed indefinitely pending further Commission action setting the compliance date for exemption certifications filed under § 64.6306(e) and subsequent publication of the effective date and conforming amendments to the rule in the Federal Register.

Please include the OMB Control Number, 3060-1285, in your correspondence. The Commission will also accept your comments via email at

As required by the Paperwork Reduction Act of 1995 (44 U.S.C. 3507), the FCC is notifying the public that it received final OMB approval on May 13, 2021, for the information collection requirements contained in the modifications to the Commission's rules in 47 CFR part 64 and modifying the language of § 64.6305(b) and (c) to conform to the compliance dates adopted by the Wireline Competition Bureau in DA 21-454.

Under 5 CFR part 1320, an agency may not conduct or sponsor a collection of information unless it displays a current, valid OMB Control Number.

No person shall be subject to any penalty for failing to comply with a collection of information subject to the Paperwork Reduction Act that does not display a current, valid OMB Control Number. The OMB Control Number is 3060-1285.

The foregoing notice is required by the Paperwork Reduction Act of 1995, Public Law 104-13, October 1, 1995, and 44 U.S.C. 3507.

The total annual reporting burdens and costs for the respondents are as follows:

OMB Control Number: 3060-1285.

OMB Approval Date: May 13, 2021.

OMB Expiration Date: May 31, 2024.

Title: Compliance with the Non-IP Call Authentication Solution Rules; Robocall Mitigation Database; Certification to Verify Exemption from Caller ID Authentication Implementation Mandate.

Form Number: N/A.

Respondents: Business or other for-profit entities.

Number of Respondents and Responses: 6,535 respondents; 6,535 responses.

Estimated Time per Response: .5 hours-3 hours.

Frequency of Response: Recordkeeping requirement and on-occasion reporting requirement.

Obligation to Respond: Mandatory and required to obtain or retain benefits. The statutory authority for this information collection is contained in sections 227(b), 227(e) and 251(e) of the Communications Act of 1934.

Total Annual Burden: 15,520 hours.

Total Annual Cost: No Cost.

Nature and Extent of Confidentiality: The Commission will consider the potential confidentiality of any information submitted, particularly where public release of such information could raise security concerns (e.g., granular location information). Respondents may request materials or information submitted to the Commission or to the Administrator be withheld from public inspection under 47 CFR 0.459 of the Commission's rules.

Privacy Act Impact Assessment: No impact(s).

Needs and Uses: On October 1, 2020, the Commission released the Order, FCC 20-136, published at 85 FR 73360, November 17, 2020, adopting final rules—containing information collection requirements—designed to promote caller ID authentication technology. The rules implement the Pallone-Thune Telephone Robocall Abuse Criminal Enforcement and Deterrence Act (TRACED Act), promoting the deployment of caller ID authentication technology, and combatting the practice of illegal caller ID spoofing. In doing so, the Order adopts rules governing intermediate providers and caller ID authentication in non-IP networks, implements the exceptions and extensions established by the TRACED Act and prohibits line-item charges for caller ID authentication.
