Supporting Statement for Survey Collection Part B_final version

OMB 3060-XXXX

October 2022

New collection entitled: Performance Evaluation of Numbering Administration Vendor(s)

Part B: Collections of Information Employing Statistical Methods:

1. Describe (including a numerical estimate) the potential respondent universe and any sampling or other respondent selection methods to be used. Data on the number of entities (e.g., establishments, State and local government units, households, or persons)in the universe covered by the collection and in the corresponding sample are to be provided in tabular form for the universe as a whole and for each of the strata in the proposed sample. Indicate expected response rates for the collection as a whole. If the collection had been conducted previously, include the actual response rate achieved during the last collection.

This collection of information does not employ statistical methods, including sampling. Nevertheless, the information contained in this Part B of the supporting statement is included to better understand the design and purpose of the surveys.

The target population for these surveys are the provider and non-providers users of the NANPA/PA/RNA/RNDA and state regulator representatives interacting with the NANPA/PA/RNA.

There are approximately 1,490 active NANPA/PA/RNA users that are service providers,

52 representatives of state and territorial regulatory agencies that interact with the NANPA/PA/RNA and 79 active NANPA/PA/RNA users that are neither service providers nor representatives of state and territorial regulatory agencies.

Each of these entities will receive three emails inviting them to fill out one NANPA survey, one PA survey and one RNA survey at the electronic portal.

There are approximately 1,060 active RNDA users that are service providers and 

238 active RNDA users that are not service providers. Each of these entities will receive one email inviting them to fill out one RNDA survey at the electronic portal.

It is expected that the response rate will be approximately 40 percent.

2. Describe the procedures for the collection of information including:

• Statistical methodology for stratification and sample selection,

• Estimation procedure,

• Degree of accuracy needed for the purpose described in the justification,

• Unusual problems requiring specialized sampling procedures, and

• Any use of periodic (less frequent than annual) data collection cycles to reduce burden.

The survey does not use a statistical methodology.

Some of the questions ask for a response on a numeric scale, while others ask for qualitative “fill-in-the-blank” responses.

The NAOWG will direct the vendor(s) to send emails to the target population described above, inviting them to go to the web portal to fill out the surveys. Each member of the target population will receive a separate email for each survey they are the target population for. For example, if an entity is in the target population for all four administrators (NANPA/PA/RNA/RNDA), it will receive four separate emails, each with a separate link to a different survey.

There is no specific degree of accuracy necessary for the purpose described in the justification. For example, because of the qualitative nature of some of the questions, the NAOWG will need to examine the detail provided in the response and the areas covered in order to determine the extent to which it satisfies the purpose described in the justification.

3. Describe methods to maximize response rates and to deal with issues of non-response. The accuracy and reliability of information collected must be shown to be adequate for intended uses. For collections based on sampling, a special justification must be provided for any collection that will not yield "reliable" data that can be generalized to the universe studied.

Two follow up-emails asking for a response will be sent during the response window for the survey. The first email will be sent approximately half-way through the response window and the second email will be sent approximately one week before the end of the response window.

4. Describe any tests of procedures or methods to be undertaken. Testing is encouraged as an effective means of refining collections of information to minimize burden and improve utility. Tests must be approved if they call for answers to identical questions from 10 or more respondents. A proposed test or set of tests may be submitted for approval separately or in combination with the main collection of information.

None.

5. Provide the name and telephone number of individuals consulted on statistical aspects of the design and the name of the agency unit, contractor(s), grantee(s), or other person(s) who will actually collect and/or analyze the information for the agency.

Not applicable because there were no statistical methods used.
