CDL Last Mile Solutions is a United States regional carrier focused on last-mile and time-sensitive delivery. Its confirmed service area is concentrated in the Northeast and Mid-Atlantic, with distribution facilities in New York, New Jersey and Maryland. For overnight delivery, CDL specifically lists New York, New Jersey, Connecticut, Pennsylvania, Delaware, Washington, DC, Maryland and Virginia.
Relevant services include same-day delivery, regional next-day and overnight delivery, retail home delivery and assembly, customized shipping, Manhattan messenger service, warehousing, fulfillment and distribution. CDL also handles business-to-business, business-to-consumer and person-to-person deliveries. Boston and Pittsburgh are identified by the carrier as expansion areas, so they should not automatically be treated as part of the currently listed overnight network.
For a recipient checking a package, CDL provides its own shipment tracking tools and publishes detailed scan histories for supported shipments. 4Tracking is a separate universal package tracking website. It can be used to check available shipment events for a CDL tracking number, but features described for CDL's own portal, such as its integrated tracking tools, should not be assumed to work in exactly the same way on 4Tracking.
How to track CDL Last Mile Solutions shipments with 4Tracking
Start by copying the complete tracking number or shipment reference supplied by the seller, sender or shipping confirmation. Enter that identifier in the tracking field on the CDL Last Mile Solutions page at 4Tracking and submit the lookup. If shipment information is available, review the returned events in chronological order to see the latest recorded progress.
CDL's own tracking records show the types of events that may occur during its delivery process. Published examples include a label being created, a CDL origin scan, a scan at a local delivery center, an out-for-delivery event, a delivery scan and delivery completion. Its official tracking pages can also show the destination and latest update. These are features and event names documented on CDL's own tracking system; 4Tracking should only be expected to display the events that are actually available for the number entered.
If 4Tracking returns no information, first compare the identifier with the original shipping message and make sure no letters, digits or punctuation were omitted. CDL's official systems use more than one shipment-related identifier, so an order reference and the identifier used for package tracking may not always be the same thing. If necessary, check the carrier's official tracking system or ask the sender which reference belongs to the parcel.
CDL Last Mile Solutions tracking number formats
CDL does not publish a single public specification defining one universal tracking-number length, prefix, suffix or character pattern for all shipments. Its official tracking pages demonstrate that a shipment record can contain both a Tracking Number and a Package Reference, but that does not establish a format rule that can safely be applied to every package.
For that reason, do not add a CDL prefix, remove punctuation or modify the number based on examples found elsewhere. Copy the complete identifier exactly as provided by the sender or shown on the shipping documentation. If several references appear on the order, use the one specifically supplied for tracking or confirm the correct identifier with the merchant.
CDL Last Mile Solutions delivery times
Delivery timing depends on the service booked. CDL offers same-day delivery for regional time-critical shipments and separately advertises regional next-day and overnight delivery. For overnight service, the carrier currently lists New York, New Jersey, Connecticut, Pennsylvania, Delaware, Washington, DC, Maryland and Virginia. These service names describe the booked delivery level; they should not be treated as a universal timetable for every CDL shipment.
Official tracking records provide practical examples of how some overnight movements can look. In one published shipment, a CDL origin scan in Kearny, New Jersey was recorded at 9:01 PM on February 11, 2026, followed by delivery in Philadelphia, Pennsylvania at 3:38 PM on February 12. Another record shows an origin scan in Kearny at 8:47 PM on March 24, followed by delivery in Branchburg, New Jersey at 12:20 PM on March 25. These are examples of completed shipments, not promised transit times for other packages.
A label-creation timestamp should also be separated from actual movement through the CDL network. Official tracking examples show that a label can be created before the later origin scan. When estimating progress, the origin scan, local delivery-center scan and out-for-delivery event usually provide more useful evidence of physical movement than the label-creation event alone.
CDL's published services are primarily regional United States delivery services, and its service pages do not present an international customs-clearance timetable. If an internationally purchased package is handed to CDL for final delivery after entering the United States, time spent in customs earlier in the journey should not be confused with CDL's domestic last-mile transit. Check the upstream carrier or seller for customs information when the parcel has not yet entered CDL's documented delivery flow.
Contact CDL Last Mile Solutions about a shipment issue
For pickup, delivery or service questions, CDL publishes the telephone number 212-243-5600 on its official service and service-area pages. The official contact page also provides a customer-support email option and lists Client Resolution hours as Monday through Friday from 8:00 AM to 10:00 PM EST, Saturday from 10:00 AM to 7:00 PM EST and Sunday from 10:00 AM to 6:00 PM EST. The headquarters address is 132 W. 24th Street, New York, NY 10011.
Before contacting support, prepare the tracking number or package reference, destination ZIP code, recipient name, sender or retailer, and the latest tracking event with its date and time. If the official tracking record shows an OrderTrackingID, keep that available as well; CDL's portal specifically instructs customers with questions to reference the OrderTrackingID shown for the order.
For a package marked delivered but not found, provide the delivery timestamp and any delivery details shown in the carrier's record. Some official CDL tracking records include delivery-location notes and proof-of-delivery information, but availability varies by shipment. For a package that has stopped progressing, give support the last scan location and time rather than only stating that the parcel is late.
Frequently asked questions about CDL Last Mile Solutions package tracking issues
Why does my CDL Last Mile Solutions tracking number show no result?
Check the identifier against the sender's original shipping information and enter it without changing its characters. If it still produces no shipment information, try CDL's official tracker or ask the seller which tracking or package reference belongs to the shipment.
What does a label-created event mean for my CDL package?
CDL's tracking records can show a label-created event before an origin scan. If no later scan appears, the tracking history has not yet shown the package moving through a CDL origin location.
Why has my package been scanned at a local delivery center but not delivered?
A local delivery-center scan is an intermediate event in CDL's published tracking histories. Look for a later out-for-delivery event; if the shipment remains unchanged beyond the expected service window, contact CDL with the last scan location and timestamp.
Does out for delivery guarantee that my package will arrive the same day?
The status indicates that the package has reached the out-for-delivery stage, but CDL's public tracking documentation does not state that every such scan guarantees completion by a particular hour. Continue checking subsequent events and contact support if the expected delivery passes without an update.
My tracking says delivery complete, but I cannot find the package. What should I do?
Review the official tracking record for any delivery-location or proof-of-delivery information, then check the stated delivery area. If the parcel is still missing, contact CDL and provide the tracking reference, delivery timestamp, destination and any delivery details shown.
How long does CDL overnight delivery take?
CDL sells regional next-day and overnight delivery in its listed service area, but the exact arrival time depends on the booked shipment. Official tracking examples show some packages moving from an evening origin scan to delivery the following day, but those individual records are not universal guarantees.
Does CDL deliver everywhere in the United States?
The carrier describes itself as a regional provider from the Northeast to the Mid-Atlantic, not a nationwide last-mile network. Its current overnight-service list specifically covers New York, New Jersey, Connecticut, Pennsylvania, Delaware, Washington, DC, Maryland and Virginia, while Boston and Pittsburgh are identified as expansion areas.
Can I use the same number on CDL's official tracker and 4Tracking?
Use the shipment identifier supplied for tracking, but remember that CDL records can contain both a Tracking Number and a Package Reference. If one identifier does not return the expected shipment, check the shipping confirmation or ask the sender which reference is intended for package tracking.
