Abstract

A valid destination address is determined. An availability request is sent to each destination address from a set of destination addresses. The destination addresses are correlated with a destination party. At least one response to the sent availability requests is received. Each received response is uniquely associated with its own destination address from the destination addresses. Each received response indicates either a valid destination address or an invalid destination address. For each received response, a value associated with the destination address that is associated with that received response is recorded. The value indicates either a valid destination address or an invalid destination address based on the received response associated with that destination address.

Claims

1-32. -32. (canceled)

33. A method for obtaining a valid international destination address, comprising:

determining a carrier type based on a requested address associated with a destination party;

determining, when the determined carrier type is a single-match carrier type, a destination address associated with the destination party and being a valid destination address; and

validating, when the determined carrier type is a multiple-match carrier type, a plurality of candidate destination addresses associated with the destination party.

34. The method of claim 33, further comprising:

determining a destination country associated with the requested address; and

verifying that the requested address is not an invalid address based on at least a portion of the requested address and based on at least one predetermined invalid address associated with the determined destination country.

35. The method of claim 33, wherein the multiple-match carrier type includes at least one from the group of an embedded-carrier-information destination address and portable destination address.

36. The method of claim 33, wherein said validating includes:

sending an availability request to each candidate destination address from a plurality of candidate destination addresses, the plurality of candidate destination addresses being correlated with a destination party;

receiving at least one response to the sent availability requests, each received response being uniquely associated with its own candidate destination address from the plurality of candidate destination addresses, each received response indicating one from the group of a valid destination address and an invalid destination address; and

recording, for each received response, a value associated with the candidate destination address associated with that received response, the value indicating one from the group of a valid destination address and an invalid destination address based on the received response associated with that candidate destination address.

37. The method of claim 33, further comprising:

sending a text message to each destination address from the plurality of destination addresses for which no response was received.

38. The method of claim 33, wherein:

sending a text message to the destination address from the plurality of destination addresses that has an associated value of a valid destination.

39. The method of claim 33, wherein:

each candidate destination address from the plurality of candidate destination addresses having at least a carrier identifier, a network identifier, a device identifier and a gateway identifier.

40. The method of claim 33, wherein said validating includes:

generating a plurality of codes each being uniquely associated with each destination address from the plurality of destination addresses;

sending a message to each destination address from the plurality of destination addresses, each message being uniquely associated with a destination address from the plurality of destination addresses and including a code from the plurality of codes associated with that destination address;

receiving a self-authentication message from a destination address from the plurality of destination addresses, the self-authentication message having a code value; and

validating a destination address from the plurality of destination addresses based on the code value of the self-authentication message corresponding to a code from the plurality of codes.

41. A computer-readable medium having instructions stored thereon, the instructions when executed by a computer cause the computer to:

determine a carrier type based on a requested address associated with a destination party;

determine, when the determined carrier type is a single-match carrier type, a destination address associated with the destination party and being a valid destination address; and

validate, when the determined carrier type is a multiple-match carrier type, a plurality of candidate destination addresses associated with the destination party.

42. The computer-readable medium of claim 41, having additional instructions stored thereon, the additional instructions when executed by a computer cause the computer to:

determine a destination country associated with the requested address; and

verify that the requested address is not an invalid address based on at least a portion of the requested address and based on at least one predetermined invalid address associated with the determined destination country.
