Methods, systems, and computer program products for preserving sequencing of signaling messages at a routing node are disclosed. First and second signaling messages are received at a routing node of a communications network. The first signaling message is received prior to the second signaling message. Next, it is determined whether processing is required for the first signaling message. In response to determining that processing is required for the first signaling message, first and second sequence identifiers are assigned to the first and second signaling messages, respectively, the first and second sequence identifiers indicating a relative sequence four routing the first and second signaling messages. Next, the first and second signaling messages are routed to the communications network based on the relative sequence indicated by first and second sequence identifiers.
